It is driving me crazy having to tooltip every single item for information about visual collecting and I have found no addons that is fully helping out on this.
There is one, but it does not support bag addons AND it does not fully function in the fact that it question marks all unusables, rather than tell if it is missing (which is available information on tooltipping the items) and should be sent to another toon for inclusion.

Any chance this addon can have "non-collected visuals" indication added as a wardrobe icon, a frame coloring/highlight or something else? I thought about just coloring, since this is an existing feature for other types of visual filters, but that would be incompatible with making a fast view of items that is collectible and wether or not they should be sent to an alt because they are unusable.

Adding some sort of highlight/showntell on un-collected visuals slots together with having coloring for unusables would be amazing for sorting through what can be collected on the active toon and what to send to an alt for visual collection.

In this process, it would be a nice to have thing, if the unusable coloring applied to all armor types not for the active class, rather than just armor types not able to be equipped.

This would make adding to your collection a lot easier. Before you sell off a bunch of things checking each one can take a little time.
