GitUI is amazing. The only caveat to many developers is that GitUI is still unusable when you GPG sign your commits, even after so many years and with functioning PRs already created. This excludes, in my opinion, a large portion of the possible users from using GitUI. However, it might still be useful for everything Git-related which does not require creating/changing commits.
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.
Not sure if you are familiar with GitHub. It is not an issue in the sense of a problem, but it is a reasonable feature one could request using the issues interface on GitHub. However, I see that such issue already exists. As expected, though, it is way down in the developer’s backlog. If enough people show interest in the feature in the linked issue, its priority can change.
I am trying to stay calm, but failing miserably. This is simply amazing. Good job!
