[Workbench] Display portable data hash, parent project, file count in Collection tables
Let's say I've created a Collection "Gemini data" and copied it into a variety of different projects. Then I created another collection called Gemini data with different data. Now if I search for "Gemini data" I get back a lot of collections with the same name, but I can't tell they are different or the same. Seeing the content addresses in the search results would be a quick way to compare them. Also, seeing the project that they are in might be helpful, as well as the number of files and Mib.
