Remove label with a single click

Problem to solve

As a user of labels,

I'd like to be able to remove a label with a single click from the sidebar,

So I can move on to other tasks quickly.

Intended users

Everyone who uses labels.

Further details

Simple quality of life improvement to the labels section of our sidebar. In order to remove a label, I have to click edit, click into the search, find the label, deselect it, and click out to apply the change. 5 steps to reach a small change.

Proposal

After I click edit, I'd like to see an [x] option on the labels applied to an issue, so I can simple click to remove it, with a single action.

Documentation

We will need to update docs and some screenshots.
