Usability issues

[GittingHubb]

Please add the option to add tags to a selection of items (now I have to add tags to each item one by one, this is very time consuming for medium-large collections)
Also please ask for confirmation before deleting a tag completely (especially if there are items that are using the tag).
I thought I had accidentally added a tag to the filter (because the division between tag list and the filter is unclear) so I accidentally deleted the tag altogether and had to (one by one) re-tag everything.

Also, please allow changing tag colors (makes things more clearer); And a NOT filter type, to filter out a single (or multiple) tags.

Thank you for this tool, because otherwise Epic Games' vault is unusable.
