You may remember back in the old days when we had Android and Sailfish OS side multitasking separately. So basically what I mean is that through one Android app you could close and switch between another. Now we have all the running apps in one view which is absolutely a good thing.
On the other hand, I've found an issue or something that I find quite annoying. Let's say that you want to open a link through WhatsApp or whatever Android app you like, and even more you'd like to use Google Chrome or Firefox etc. Android browser. The thing that I find quite annoying is that the link is opened on the same tab (with WhatsApp in this example) and then when you close the opened browser etc. then it hangs there in background, which can cause battery drain. Would it be better if the action created a new tab with Android side apps like it does with Sailfish native apps? Then you could close the new tab or keep it open if you really need it, instead of having an Android app there hanging in the background.
I consider this to be annoying because you have to manually search and close the opened app after you have used it. And this "issue" occurs with any Android app because they are opened in one view not in separate tabs. And this only occurs with the case when you're opening an Android app through another Android app.
Briefly, it would be nice to have a view which would show these Android applications. It could be like back in the old days or then like that every Android app would open in a one tab on Sailfish multitasking view.
I hope you got my point and I'll try to answer your questions as much as I can.
