I would be nice, if one could just cancel an operation in progress (i.e. a selection of a couple of hundred thoughts) instead of getting the message: "You must wait until this operation is complete."
BTW: "must wait" (???), how about "These operation cannot be interrupted, please wait."
I'd rather kill the process with process manager instead of wasting five minutes.
