• Fixes ResourceName not saved #82333

Needs some adjustments to the note. Also, could you please amend the commit message to follow our prefer format (starts with a verb describing the action, followed by the subject of the change)? The current title of the PR is a good option.

could you please

No, I could not. I've had my suggested change shot down three times now, for a one line doc change, and now you want the commit message changed too (not mentione after it was ignored for months). I've lost all enthusiasm for driving this forward. Clearly things must be done exactly right here, and I don't know how, so you can sort it out yourselves.

That's understandable. We have both a significant backlog to review with limited resources, and high quality standards to ensure that what gets merged is correct and does not add to tech debt that would be hard to manage with scale.

It's totally ok to opt out of the process if it's too cumbersome, we understand it's not for everyone.

Do you mind if we take over this PR to do the final touches ourselves so that it can be merged?

Feel free

Thanks! And congrats for your first merged Godot contribution 🎉
