I just had an issue where I deleted an entire folder of tags
How it happened:
I had some buttons selected in the designer, they show up as selected. I also had a folder selected that I had just minimised by pressing the - button on the left of it, this shows up as selected in the tag browser. I expanded another folder, this did not remove the focus from the original folder and then decided to delete the buttons in the designer (which still show as selected). I hit the delete button and after clicking yes, the entire folder disappeared.
I admit I should probably have read the dialog box but it appears whenever you delete a component so it becomes something you click through automatically.
Unfortunately pressing ctrl-z only undoes changes to the designer, not to tags so I was unable to recover the tags and had to rebuild them.
So my request is to make it so that selecting tags or tag folders removes the focus in the designer and vice versa. Just to prevent this from happening in the future (I admit I’ve learned my lesson). This is version 7.2.4 so not sure if its already been fixed.
