General: Formatted Text throughout - also for comments, Notes.
General: Deep links, linking documents as comfortably as linking tasks.
Calendar: additional field: Location for calendar entries (ical standard?!)
Address Book: faster address book a la reload as you type; quick display of all important contact fields; copy full contact info to clipboard; pastebox to fill in a contact with a few simple validations trying to automatically extract name street, zip, city etc.
Notes: The notes list cannot be ordered. Notes and comments can't have styled text. Comments should be foldable for some sort of “expanded list” view of all current notes in the order of update - that, then, would essentially be a forum application.
General: Archiving projects so that they disappear from the various treeviews.
Documents: More preview visualisers for documents, (preferrably flash-based) i.e. viewing PDFs, or CAD files right within the browser, in-line.
General: Would need more functions for bulk-editing objects, e.g. exporting links, changing workspace, changing properties of multiple items at once, etc. - could this be a centralized function set underneath the search function?
Scalability: Admin Users panel shows only about 6 Users at a time - the layout could be much more compact.
when allowing users from another company access to a workspace, there is a folding menu that takes up half a screen. And it doesn't fold back, so when i want to grant access to 5 external users the page becomes much too long.
