I will take note about what you mention. Certainly, I can see the TAB not working as expected, and, need to investigate about the icons for Android that you refer. I can't promise a date right now... but I will / need / want to take a look at this when possible, Michael.
I publish right now a new DecSoft App Builder release wich fix the bug with the TAB key. Taking a look at the adaptative icons in Android, what we do is to follow the Apache Cordova documentation, so, if you experience some particular problem, please, post it here, so maybe I can find some information about that.
Everybody can read the DecSoft support forum for learning purposes, however only DecSoft customers can post new threads. Purchase one or more licenses of some DecSoft products in order to give this and other benefits.
