confirmation before closing the create category window

Upon my first time using this app, I spent quite a lot of time trying to create a category for pose keypoints and linking everything up. At one point I accidentally clicked off of the create a category window and it closed with no confirmation.

I think either disabling the feature that closes the window when the user clicks somewhere else, or adding a confirmation dialogue if there are unsaved changed would be a good addition.

I have now realised that the category is not immediately deleted but can be recovered by clicking on create category again. Although this is not obvious and what a first-time user such as myself might do is click off of the page and then lose the unsaved data permanently.
