I knew you will take tags up too! 😁
Doesn't seem to work in every situation for me when unselecting tags.

After single selecting I selected two tags, that worked. But when un-selecting tags notes wasn't filtered correctly. I guess that's because only one tag was selected any more and I clicked on the tag that I wanted un-selected. I don't know how to get around this. 😬

It seemed pretty straightforward after I looked into it 😆
