Reload tool scripts on save

[Vitorgus]

Every time you make a change on a script with the tool keyword, you have to close the scene and open it again for the change to take place.

The usual workaround seems to be binding a shortcut to reload the scene, but one still has to remember to use the shortcut at every script change. And if you don't, you're gonna spend some time debugging and worrying on what went wrong, when actually everything is alright and you just forgot to reload the scene.

The idea would be for the editor to auto reload the scene when you save the script. It would remove the need for the developer to be actively remembering to reload the scene at each save, and focus more on developing the game. This feels like something small that would be a great QoL improvement for those who use tool scripts.
