I'm way beyond the child raising age, but maybe closer to needing a kidney so this could be a good trade. 😃
When I restarted this, around 2 years ago now, one of the goals was the eventual support for mobile. The main problems with that are related to the UI. Better support for smaller screens and touch interface. As I mentioned, I use a multi-platform development tool called Juce which has support for both iOS and Android as target systems. So in theory I just recompile it for Android, and it works. In practice though, the UI would be barely usable in its current form.
The UI has always been the last thing in Mobius to get any attention, and it is long overdue for a redesign. When I get to that, I'll be doing it with mobile in mind, but there are a few other larger features I'd like to finish first, before I spend a year doing nothing but UI work.
I'm retired now, and I don't like golf or whittling or whatever the hell else it is old people are supposed to do, so this is my full-time job for awhile. It'll get there eventually but it's hard to say when. I really need to post a "product roadmap" that outlines what's on the list and let people vote on that.
