I use this PR template a lot and I can make a PR to add to the repo if it is good enough. I believe having a template makes documenting pull requests much easier.

I remembered that I should add ruff and mypy versions to optional-requirements.txt. I did just that.

Hi @omar-abdelgawad. I tested here. I'm using Python 3.11. I'm having this error:

  File "/var/home/thiago/Sources/github/invesalius3/invesalius/presets.py", line 33, in <module>
    class Presets:
  File "/var/home/thiago/Sources/github/invesalius3/invesalius/presets.py", line 106, in Presets
    def SavePlist(self, filename: str | Path) -> str:
                                        ^^^^
NameError: name 'Path' is not defined

If I add from __future__ import annotations on the top of invesalius/presets.py it works.

Other thing. I think the tr part is better to be in other PR.

Hi @tfmoraes . I apologize for not noticing this runtime error. I read the docs and evaluating annotations at runtime happens only with function parameters which I missed. I tested it now and it works. I also reverted the changes regarding tr using git revert and then changed it also in presets.py and included this change in the same revert commit using git commit --amend. I thought this would make it more concise but please tell me to fix if it confusing or if you think I should do a complete git rebase -i.

Thanks @omar-abdelgawad. Merging it.
