Easier delete multiple tags
There is an easy way to delete a tag from the system by selecting the tag (as when filtering records that have that tag) and then clicking the "Remove tag" link:
The problem is that if you want to mass delete dozens or hundreds of tags, you have a lot of clicking and mouse-moving to do. Select the tag on the right of the screen, clicking on "Remove tag" on the left of the screen, confirm that you really want to delete, and so on,
One way that is perhaps slightly less laborious is to use the bulk edit function as described here, but each tag still needs to be selected in a dropdown menu which means a lot of clicking and scrolling if you have a lot of tags.
So I'd like to suggest to have the "Delete tag" link not only when a single tag is selected but also when multiple tags are selected. In that way, one would just multi select the tags to be deleted by clicking on them in the tag-list and then clicking "Delete tags" and boom, they're gone!
Currently, there is no such button when selecting multiple tags:
