Hey there. Just started my journey with lemmy and am not so much a fan of using it in a browser. Is there some linux app I might try? (I use arch btw.)
Welcome. Sure, Linux Mint's WebApp Manager or Peppermint OS's Ice are here for you. But jokes aside, sadly, no. Lemmy does not have a native Linux application as of now. But you can make use of the fact that the browser UI is a PWA which can be installed like a regular app as well.
Proper PWA support isn't in v0.17.3 (although mobile browsers will let you add it as an app). However, PWA support was merged into the main branch. I'm not sure which release it will be a part of though.
