1) Creating a native ChromeOS app would require pretty much rewriting the entire application, as a ChromeOS app is nothing like an Android app

With approximately 30 years of software tools, OS, and applications design and development behind me, this gives me some insight into the design and implementation of MobileSheets.

I think I may have been too harsh in my expectations, and this conversation has led me to change my approach.  So if MobileSheets is more specifically designed and tested to run on Android, and not reliably adaptable to ChromeOS, then I just need to go in that direction for a dedicated sheet music system.  I'm now thinking of moving towards a relatively large Android tablet along the lines of a Samsung Galaxy Tab S7 with a 12" screen.  The cost/performance ratio is quite low, I can expect MobileSheets to perform well without drama or workarounds. The full-blown tablet approach offers some other advantages as well.  And I've already learned a lot in the process of experimentation with Chromebook attempt.
