[FEAT] Multiple Stack Layers

[RUGMJ]

Is your feature request related to a problem? Please describe.
It's annoying to only have 4 apps in a stack max

Describe the solution you'd like
When a stack is expanded if the main app is swiped up on again another layer will be shown, this would allow more than 4 apps to be added to a stack

Describe alternatives you've considered
Allowing more than 4 apps in general, however this would be annoying as you'd have to move your finger much further to reach the icons

Additional context
