The new Basecamp is great, and I know you are working on the upgrading process. A couple things that would be nice are
(1) An option to de-privatize all “Private” items in a projects, in lieu of a method of being able to import them.
(2) An option to notify All Users of a project when it is imported.
I find myself manually doing these two steps on each project that I do import, because not having Private items in the new version is not a deal-killer for most projects (the loop-in feature neatly replaces most of the need for this, although they are do not fit exactly the same scenarios), and everybody does have to be notified when the project moves 🙂 although I appreciate that it is not automatic.
It would also be very nice to have a one-click import for all eligible projects. It takes a while to go in and click on each one, and wait, and click, and so on.

Everything’s migrated except one project… Where I’ve gone through and looked and looked for that last tricky Private item and haven’t found it yet. Aaargh…
