Did a quick search through the forums & didn't find anything related to this.

I want to request "Toggle All" options for "Art Type" & "License(s)" in the search pane. These would cause all options to be either selected or de-selected at once.

Reasoning: For me, using my mobile device, it can be a slight pain to go through the checklist on my small touchscreen. But, I would think that desktop users would like it as well.
