I'm (smilingly) very confident this suggestion will fall on deaf ears (since it's just the opposite of the app re-badging efforts currently in vogue).
Yesterday I was battling the two panels on my Bible! app. I wanted the top one to be my reading, and the bottom one to be my research-y stuff. Unfortunately the bottom one is hard to manage (and is also hard to manage in the other Bible software competitors too).
So I thought I'd download FaithLife, and operate with another 'window'. I already have Noet and Vyrso occupied with my journals, etc. But Faithlife was altogether structured differently (and validly so given its objectives).
Here's my suggestion: hide a switch somewhere (in Logos5?, iOS settings?, etc) that would allow using the Logos apps relative to one of Logos' app standards (eg Bible!, Vyrso, Noet, Faithlife, etc). That way you could spread your study out on more panels. Logos5 already accomodates the idea (new in L4), and it's a good one.
Currently (and I really hate to say this), but the iOS apps are similar to Libronix (ah, so heavenly a piece of well-written software!!). Everything has to fit on one window, like 10 people in a VW bug.
