When you long hold, it gives the option to visit the community and block community. A third option would be to subscribe to the community, since I know there are going to be many I want to just add.
The other bug/optimization is that, when I followed the link in the Thunder app’s about page, it loaded this community as a web page instead of going to the community in the app itself.
The side bar is currently being worked on and looking like it’s close to completion.
The opening Lemmy links in browser is something we’d like to fix. I don’t think anyone has gotten to it just yet though.
