Back when Sencha had Sencha Touch (2.4) you could set startupImage and icon to define images for startup the app icon for your app.
Currenctly I'm moving from Touch to ExtJS (6 modern toolkit) and this doesn't seem to exists anymore. Also in the changelog and forums I can't seem to find the answer. Does anyone here know something to get app loader images defined and an app icon?
I do not use Cordova, it'll be a normal webapp. When putting the app on your homescreen on both iOS and Android the defined icon will be shown and when starting the app from the homescreen, the app would use the defined splash screen(s).
