When I'm asking a question and adding tags, the names of individual tags I enter change into icons. It would be nice to be able to click on those icons to open their information page in a new browser tab (since I would not want to discard the question). That way, I could quickly check on what sort of questions use the tag, and also check more thoroughly on whether I'm writing a duplicate.
Currently, I must open the site in a new tab, and either copy and paste or type the given tag name into the search bar of the new tab. That should be doable in one click.
The icon for turning tag icons into text should appear on the far right of the tag bar. (I think it is a very rarely used option.)
Eventually, there should be a drop-down field that offer an option to change name, and open a new tab on a page listing the questions with the given tag.
