Sometime in the last few days or so (I think), I lost the ability to drag anything into the Note field. Initially I thought it was because I was running in Compact mode (nope, not it).
I’m running 2.0.2 r. 212379 now; anyone else seeing this? I’ll file a bug in the mean time.
Update: Upon further testing, this appears to be the same limitation we’ve had with Mail for a long time: the inability to drag a message if it’s being displayed as part of a “Conversation” (“View > Organize by Conversation”).
It’s unclear if this is a Mail issue or an Omnifocus issue.
