We almost exclusively use projectplace document storage for MS office files - either excel sheets, word documents or visio diagrams.
One feature of MS office is the ability to reference other documents. This is useful especially in excel.
Projectplace makes using this really hard.
This means we have to include all data from other spreadsheets, making sheets larger, or that you simply cant work that way, which is not good.
I propose that projectplace figures out a way to support links/references between documents. I can think of a few options, but I bet your great devs can think of some options too.
I have seen this requested a few times before.
