Got it. Seems to be exactly that.

Apparently AS has most of the features, found in the other clients, but… buried under the pile of a context menus! — Like in order to use it efficiently (or use it at all) one has to read a few hundred pages long Operation Manual… as if it were an elaborate industrial equipment :)

I also like the colored "dependency graph" of a conversation. — Cool feature.

@amiloradovsky I have word suggestions in my two hardware devices by different vendors and different Android versions, and in Android emulator also. I use Default keyboard apps. So maybe it makes sense to file a bug to your keyboard's developers?!

@amiloradovsky This is natural Android behaviour: I didn't change anything here. After update the "ChangeLog" screen _is_ the first activity, and in this case going "Back" means exiting the application. This is how Google recommends to work with "activities" (I.e. don't change natural order of activities...)
I understand you, but I'm not sure that "Back" to Default timeline would be more intuitive for an ordinary Android User...
