Explain the problem as you see it
Just right-click a Supertag and get the option to pin it. Would make it super easy to pin Supertags.
Why is this a problem for you?
It's a bit too much work simply to pin a Supertag to have to go to the Supertag page and go to its options, when it can simply be done from the right-click menu. Cognitively it is just a single action, but in the UX it takes too many steps, and even needs new panes to be opened and closed.
