 - Please do not open PRs to "discuss" possible solutions or to "get feedback" on your code. I simply don't have time for that.
 - Pull requests for the MAIN branch will be closed.
 - DO NOT include translated strings in your PR.
+- PRs (or parts thereof) that only fix issues inside code comments will not be accepted.
 
 If it feels necessary to open an issue first, please do so, before you open a PR.
