We myself, @E_Sch, @desertblade are kinda at a development stand still at the moment.
We have been optimizing the best we can but we continue to keep having issues saving the app in the IDE once it’s byte size goes over 500Kb.
The only other option would be to split the app into multiple apps requiring users to reconfigure and adding far more complication to the whole experience. or to remove existing features from the App.
It would really be helpful we could see an increase to something like 750Kb for now.
I know we aren’t the only SmartApp that has reached this limit. @ady624
