IPad multitasking

I'd like to be able to use slide over mode to have Soundbrenner app playlist next to my music charts.

Changed the title from "iPad multitasking" to "App: iPad multitasking"

This would be a nice feature to use with forScore. When I switch to the SoundBrenner app and then back, forScore pauses for a second or two while it does whatever computation it needs to do when coming to the foreground. If multitasking were enabled for the Soundbrenner metronome app, then I could quickly change the tempo without having to wait for forScore's foreground computations. Of couse the best option would be to allow forScore to control to the SoundBrenner pulse! (see other suggestion thread)

Since iPadOS 26 the OS itself supports true multi-window, so in practice this request is solved.
