Thank you all for providing constructive feedback. I will go through it in multiple replies to keep it trackable.

Now, before I start, I want just to remind that there is some way before we hit 2.0 version

Let's start with the crashes.

On my device (onyx, 3GB RAM), I occasionally see it not starting from launcher (WhoGo and, later, Pure Maps). I will check next time whether app process from earlier start is still working. You could try to do the same (See corresponding discussion at WhoGo thread, around https://talk.maemo.org/showthread.php?t=100253&page=16)

In addition, sometimes, when starting from terminal, there are some exceptions thrown in what looks like C++ (Mapbox GL plugin, Mapbox GL itself, or something else, no idea).

However, I haven't experienced crashes while running. To me, it sounds like OOM kill and not much I can do about that.

Let's keep an eye on it and when you have some reproducible info, please open an issue.

Will go through other points separately...
