Thanks! Didn't except so much third party commits/pull requests during my holiday 👌

Hahah yeah, sorry about that, I missed it, it was calling save_geometry() both on destroy event and delete event, somehow when positions are saved from both events they are not saved properly (when close to tray option is disabled).
It was saving x and y as 1 always.
Have no clue why though :)
Anyway, there's no need for destroy event, I tested it and it works for sure now.

Okay. Such "bugs" can be very annoying when they're not be found. Luckily you have taken this work for me :)
