It would be beneficial to be able to drag an email attachment (or multiples) directly from an an email into documents tab of a superior item (project, deal, etc.). Today, one must drag it to a folder or desktop then drag it into EWay. If it could be drug directly, it would be easier to use EWay as the project and deal repository. Possibly it wasn't designed for these purposes, but it lends itself to this quite nicely.
I would only add to this that if one uses the Document repository in EWay that it should also be easy to open from Eway, edit and save back into EWay directly. I believe this too is problematic today.
