Give me a moment, I may have screwed something up. Double checking. It's my first time doing this.

Everything's tested and works, but the package version needs to be bumped from mcomix-1.2.1_1 to mcomix-1.2.1_2 in the template, which I forgot to do. Looking at other pull requests I think I also didn't follow the naming convention for my commit. Let me know if I should make a new pull request of if it can be fixed up on your end.

please bump the revision and fix the commit title. There's no need to open a new PR. You can just amend your commit (make the changes, git add, git commit --amend) and force-push (git push -f) to your own branch to update it.

There, that should do it.
