Wonder if it is possible to create a button next to "Display all tags in this library" check box (in the left pane) that allows unchecking (inactivation) of all tags?

Scenario: After having found an item using tags, I have to manually uncheck all tags before initiating a subsequent search. This can be time consuming if one maintains a large tag library (the small size of left pane does not allow visualization of all tags; one has to scroll up and down to find activated tags in order to uncheck them). This is worse if several tags were used during prior search.

Many thanks!
