Yo! I've been working on a few new things.
First of all, I added support for some of Lemmy's settings. You can now change most things (except for languages, avatar/banner images, 2FA).
I also added a new markdown editor I built this morning. It's pretty similar to the one on the official UI, but at least in my little experimenting it feels a bit less buggy. Nonetheless I wouldn't be surprised if there are some issues so please let me know if you run into any problems! It doesn't yet have hotkeys (like ctrl+b for bold, etc), I plan to add those later.
I wanted to add image uploading, but unless I want to proxy all image uploads like Voyager does I'm going to have to wait for a solution to lemmy#3567.
Edit: I added hotkeys for bold and italics, whatever the normal one for your OS is.
Just tested it. Love it! Thanks a lot for the answer and specially for the quick implementation.
