"Some features are marked at", I think you meant "as".

Also, seems like the best, and only features I need are gone.

I wanted to be able to backup, or import/export to share between characters, but every single feature says "abandoned".

Just to clarify, abandoned doesn't mean gone. It means it may work, but if it's broken, I'm unlikely to fix it unless it's trivial
see it as a disclaimer to reduce expectations 🙂

sharing between characters is something I'm considering putting back on the "actively supported" list (and yes, that also means that it works perfectly fine last time I used it)

For me personally, extended macros and syntax highlighting (and keybind-only macros perhaps) were the main reasons to offer to maintain this addon
I don't have a lot of time or motivation to work on other features, but other developers are more than welcome to pitch in 🙂

(and I'll fix the typo, thanks 👍)
