I figured the Windows 10 version was more important than tackling that issue at the moment. 

I'm not sure I agree with that.  

MS started out as an Android application and most users here are using Android-based tablets.  I even purchased a tablet (in fact, two tablets) for the sole purpose of running this software and I wouldn't mind betting there are other users who did the same.

If someone is really desperate to run MS on a Windows machine, there are several Android emulators out there.  My own view is that, until touch screen Windows machines become the norm (and we're a long way from being there) there is no advantage in running MS under Windows.

I understand why you would want to expand the user base but to delay development of the Android version in favour of a Windows version seems to me to be letting down your existing (and loyal) users.
