It's funny how our expectations have changed. I am keen to like this app simply because of who it's from, Hog Bay, who made one of the first Mac apps that really inspired me to how different Mac software could be back in the 2005-ish era. That was WriteRoom, and I used it on my second-gen Intel running Tiger and Snow Leopard.
It was a blast from the past! I really enjoy looking at sites from that era - I'm thinking of setting up a proxy through the Internet Archive (several tutorials online) to use with my lampshade iMac running Snow Leopard.
UI, UX, websites, software -- it was a good time and we've lost a lot.
I'm fine with that. Newer OSes contain new features and APIs, and I can totally understand a developer wanting to build on top of some new feature instead of having to reinvent it themselves. Sometimes that's inconvenient for me, although I try to keep all my devices current. But if a dev wants to require an OS version that's shipped with every M1 Mac that's ever existed and chooses that as their cutoff, I get it.
I am on 10.14 because there are some 32-bit apps I can't replace (either because there are no 64-bit versions, for instance some old emulators, or because there are but they cost money, or there are but they have other changes which I don't like. MS Office is an example of both of the latter.
It does work, but it's a little clunky IMHO. For instance, if you press Return in the middle of a line, I expect it to split the current paragraph into 2, but not in OutlineEdit (or Outlinely or OmniOutline).
