We'd find it useful to be able to add files to existing items using the desktop uploader, rather than the uploader creating a new item for each upload.
I'd also like to support the idea of all members of a Project having the ability to edit the metadata on each other’s unpublished items. I think you've had this request already.
Both of these would help us when working with large, complex datasets with more than one author.
The second one is already being looked at, you are right. The first one i am not sure on, I'll investigate with the team at an appropriate juncture and return.
I also vote for the 2nd item - the ability to edit the metadata on each other's unpublished items. I'd also go a step further and ask that "super collaborators" on a project be allowed to remove items uploaded by someone else in a project, e.g. replace an item with a new version. This would probably require a 3rd role for projects.
Also agree re the ability to edit metadata. Falco's proposal looks ideal.
RE: "I'd also like to support the idea of all members of a Project having the ability to edit the metadata on each other’s unpublished items."
Please consider making this a Project or Group toggle and not the default. For those of us who are using Projects as an ingest method this could complicate somethings.
Similar to this thread, the ability to update or upload files to existing items using the ftp uploader would be really helpful. Currently the ftp uploader creates a separate item even if the items have the same title. It would be nice to be able to upload to an unpublished version on a public item. That way I could upload any updated files using a script after I create the data.
