I know the names of some Impression/Clarity presets so can do a search for them but I feel really sorry for anyone who never owned the original plugins.
What I'd really love to see is an option to disable thumbnails so we can just have a 'text menu'. Some of the older plugins have popup previews but there's an option to disable them. This leaves a menu with a list of categories - click on the name of a list and it opens up to a list of preset names. If we want to see what a preset does we just click on it and it shows the result on the actual photo we're working on.
I find thumbnails bearable in the Impression/Texture Effects plugins because the presets are divided into categories. Even so, I would have preferred the option to have a text only menu to save endless scrolling down the lists.
