P: collapse all preset categories

Hello,

I m playing around with some presets and it is tiresome to scroll through all of them to get to the one I want.

They also remain open once you click on the triangle so the lists grows to huge sizes.

The simple solution that I would like to see is to be able to ALT click the triangle next to each preset category, and that would collapse/expand all of them, the same way you do with the Folders panel in the Library module.

Thanks you so much!
