I submitted the initial version of Multi to HN 2 months ago [0], and the response was much larger than I was expecting. Initially, I just built Multi for my personal use, so I cut quite a few corners to get something that worked. When I saw that other folks were actually trying it out, I decided to put it in the work to make the whole experience a bit nicer.
What I'm excited about most with 2.0 is that Multi is a proper macOS app itself, with a UI for creating other apps. That makes the install process much simpler (it's a normal .dmg) and streamlines future updates (install the new Multi "runtime" app and that's it—no need to update each of your generated apps manually).
There are a bunch of other improvements listed on the release page[1]. I'll keep an eye on this thread and answer any questions I can!
