Hello,
I am a beginner too in Mobi1,
but I think you can not import in your mobi1 project what you modify directly in your HTML or JS files.
I think that if you modify your project in Mobi1 software, you will loose what you personnaly did…
But this is to confirm…
And I have the same questions / problem as you finally… what I wil test in the newt days…
