On opening Zotero standalone one can add some columns to view eg Title, Creator, Item Type etc but it would be very helpful if one could see which Collection they are included in - the only way I can see to do that would be create a tag with the collection but this is very laborious and not worth it. I really don't understand why this is missing.

It's not in a column because item<->collection is a one-to-many relationship, so displaying a list of unbounded length with no inherent order in a single column is illogical.

*not least because the way they currently work they're almost completely unusable for people with special accessibility requirements.
