I personally wouldn’t want it to be like the Unused option… unless we had the option to select which Assets to delete from the shown Unused Assets. It could just be the ctrl select highlight all the ones you want, then delete. OR make it so that unused assets fall to the bottom and used assets stay pinned at the top… just my thoughts.
The ability to clean up interactions, organize, group or something also. It would be nice to be able to have some better organizational abilities within both Asset Manager and Interactions. I think both would improve users workflow within Webflow.
