no way to quickly navigate through a long list

Just my guess, but I believe such component already exist, but Jolla disabled it for now. If you look through the source of SilicaListView, SilicaFlickable etc, it has a component commented:

/*
Disable until works reliably (JB#6502)

QuickScrollArea {
    anchors.fill: parent
    flickable: flick
    margin: Theme.itemSizeSmall
    minimumVelocity: Screen.height
    enabled: quickScrollEnabled && flick.flickableDirection == Flickable.VerticalFlick

    onScrollToTop: FastScroll.scrollToTopGesture(flick)
    onScrollToBottom: FastScroll.scrollToBottomGesture(flick)
}
*/

Based on the coding, it should be an item that appear when you scroll over the list very fast (minimumVelocity), then it offer a way to scroll to top or bottom (onScrollToTop/onScrollToBottom). QuickScrollArea is code in C++ not QML unfortunately so we can't view the source for it.

Not actually a replacement for the other suggestions in here, rather an addition but IMHO a huge user experience improvement when scrolling:

I'd love to have a scroll momentum behavior similar to lists in Android, i.e. when giving a long web page a scroll momentum and then do the same gesture again (while already scrolling), adding more momentum to the scroll and thus accelerating it. Currently the second gesture is more like decelerating the movement for a moment, just to accelerate again.

Reaching top and bottom is implemented but what if you want to reach a certain point (ie. letter M) in a long list?

There was another idea here for zooming which might work here: press and hold on the right (or config:left) side of the screen and you get scroll arrows. The speed you drag your finger up/down gets you up and down a list. Bonus feature here is you get that numbered/lettered navigation that helps you know when to slow your drag or stop.

This answer is more for app developers.

If you want to use the People App style navigation for long lists (not perfect but significantly better than not breaking it up alphabetically) then I have broken the menu out of the People App into something easily integrable into another app.

It would be great if the Silica devs packaged it up and offered it by default in Silica, but until then this can suit.

Two ideas about long lists came to my mind:

1. Like in new Xperias' Gallery (or Album, I don't remember) - resizeable icons of photos/videos/other elements of grid, using the same gestures as in zooming/unzooming things. You can make them smaller, so the list becomes shorter.

2. Scroll bar like in Symbian/MeeGo - I don't know how it works in MeeGo, but in Symbian there are letters in the middle of the screen on lists of contacts, albums, music tracks etc. or dates in Gallery. This could be used everywhere where things are automatically sorted.

And, of course, making lists shorter by using folders for example. But this suggestions is rather for users, not Jolla itself.

I thought about that some days ago, especially moved by the complaints of users who wanted to use the pulley menu while being in a long list without needing half a minute to scroll down/up the whole list.

A maybe good solution for that could be using double-finger gestures. At first I thought about something like that, but this doesn't help in the case where you just want to navigate through that long list. Instead of that, I see some possible solutions that would involve pulling up and down with two fingers, each one with its pros and cons:

• A "flick" (a fast pull) with both fingers leading to a faster scrolling than with one finger; that way you would use two fingers when you are far from what you're trying to reach (the speed could depend on the speed of the flick gesture, multiplied by some factor), and when you are near to it you only use one finger and scroll in a slower, more precise way. That would be very natural and would integrate very well with the gesture-based nature of the OS. The main limitation that I see is if a list is REALLY huge, the user not scrolling fast enough or doing it so fast that he misses what he was trying to reach.

• The second is my favourite one, though it's not so natural. When you pull the screen with two fingers, it would go down and up a fraction of the total list equal to the fraction of the physical screen travelled with the fingers (just like with a scroll bar, maybe inverted not to break the feeling of "pushing" the screen that one would get by doing it with one finger). That would allow scrolling huge distances fast and getting easily to the pulley menu. The bad thing is that, unless the user is really precise with the fingers, when used to reach a specific part of the list it would require further correction by scrolling with one finger.

• The last method is "copying" a tool used in desktop pdf readers and web browsers where clicking the mouse wheel enables a function where if you move the mouse "up" or "down" the screen scrolls at a speed that depends on how far you have pushed the mouse. If that was activated by touching the screen with both fingers horizontally parallel and moving them up or down, it would allow travelling through the list either fast or precisely, depending on how far from the point where the fingers first touched the screen they have gone.

Maybe there are more and better ways to use two (or more, since the screen accepts up to 5) finger gestures. In any case, I think that it's something that could be seized and should be useful in cases like this one :) By the way, I was worried that using two fingers could interfere with the zooming function in browser and things like that, but since the screen is even able of handling 5 fingers at the same time, I guess that the associated software will easily be able to know if both fingers are moving in approximately the same direction or in opposite ones.

In my opinion scrolling is still far from being a nice experience in long lists, webpages... The app SMPC has a very nice implementation, maybe this can be adapted.

It works more or less like a scroll bar every file/web browser uses on a PC. You go to the right edge of the screen and moving your fingertip results in scrolling through the list. Getting to the top or bottom of the screen means to get to the start/end of the list, of course you can stop anywhere in between. On top of this there is indexing, i.e. number or first character of an item is shown matching the current position in the list. It works fine for at least some hundred items. Its fast and precise enough.

1.0.7.16 Saapunki includes a method to quickly scroll through a long list. I suggest we close this issue.
