Starting CT with a weak network connection or offline is a pain in the ass, if you use the Proz.com Plus license. The handshake takes its time. This is especially the case when you are doing things that require a restart (changes, key bug under Mac).
Perhaps there could be a token that allows a couple of new starts (3? 5?) offline.
Another issue is that CT opens the license dialog box once for every resource that supersedes the free limit (5 resources = 5 dialog boxes to click).
