When creating custom app settings for buttons it would be neat to be able to choose a template previously made by the user, or to just choose some previous app or general settings to inherit the options from and keep customizing from there, or of course starting from default settings as the current only option.

Creating macros aside from just keyboard shortcuts

Sharing custom app settings with others and being able to download the templates which can be further customized.

When launching the app it requires to click on the device first in order to be able to move, minimize or close the app's window. Perhaps enabling such window control from the start :)
