Add the ability to force dual panel at any dpi (1/2)

PS5: fix 56 errors by adding a '}' on line 174
     fix 12 errors by adding eroneously deleted colorpicker import
     fix the remaining errors by removing the onResume, which was a relic of our old navbar alpha implementation that resurfaced somehow
PS6: differentiate the 2 dual-pane modes more clearly
