I found I can't change my mod ID in the workspace settings. I know that that's on purpose, but it's really annoying, because it means that even if I want to reset the workspace and use it for something else, it'll always be stuck with that name.

Issue description
The reason for this is because changing the mod name from testenvironmentmod to custom mod name introduced many bugs. Now we use fixed names to avoid these bugs.
To reset workspace, go to MCreator tab and click Clear current workspace. When you click this button, you will be asked for the modid again so a new workspace can have a new ID.
