It happens to me quite often that I read some e-mail or web page and then suddenly the screen shuts off. Then I quickly want to continue reading but I get annoyed as I have to double-tap + swipe-down + tap-app.

There should be some kind of remorse timer kind of feature for the auto locking / auto blanking screen so that if you immediately wake up the screen if would not show the lock screen but continue to show the app exactly as it was before the screen turned black.

Maybe a five second delay between screen goes off and lock screen activates?

In comments it's suggested to dim screen before shutting it off. That would be OK.

this is mentioned in this 4th comment. Considering that, i kind of consider this duplicate.

Well, I see those two as separate issues:

getting back to last app should be much faster than it is now (current setup is IMHO pretty ridiculous)
a clever idea to use remorse timer to indicate screen will go to sleep

I think this would be best solved by warning the user by dimming the screen significantly 5 seconds before locking down. (Also I think this is how N9 did it ;-).) There are other questions open about returning to the last application after device is locked.

My Jolla actually dims the screen before shutting it.. it gives enough time to tap it

The logic for automatic blanking is as follows:

1) from lock screen:

display blanks after 5 seconds of inactivity

2) from app ui:

after 30 seconds of inactivity -> display is dimmed: tapping anywhere on screen -> back to app
after 5 more seconds -> display is blanked: double tap -> back to app
after 30 more seconds -> lock screen is activated: double tap -> shows lock screen

At the time of reporting (Dec 2013), the 30 second "grace" period after blanking was not implemented yet and there were problems with processes getting out of sync regarding "screen lock is active" status. This led in to incorrect blanking logic to be used (blanking without dimming first, not blanking at all, etc).

At the moment when automatic display brightness is used in dark environment, further dimming by lowering backlight brightness might not be possible -> cyan led is show to give pre-blanking warning in that case. Update10 includes a fix that will also fade graphics towards black -> there will be visible dimming even in low lightning.

I've tested this with SailfishOS 1.0.2.5 and it seems that the screen does not automatically turn off at all if you have any app or the home screen open. Now screen turns off automatically only while the lock screen is open.

I've seen this behavior as well and I believe it's a bug..

I just tested it, and it does just like before 1.0.2.5 upgrade; slowly fades the screen before shutting it.
