Idea: Recently used toolbox filter

I find myself using many of the same UI widgets over and over. I do use the quick add bar quite a bit as well as the filters. However it still takes extra steps and I was just thinking of ways to get even quicker access to a list of UI widgets.

Recently used toolbox filter:
Add a new UI widget filter to the existing list called "Recently Used". This is a dynamic list that is comprised only of UI Widgets that are currently used in the active mockup.

For example:
If I have a mockup with a dialog, paragraph, and an search box. Then clicking the "Recently Used" toolbox filter would show only widgets that are being used in my active mockup, and I would have very quick access to them.
