Improve check in dialog (once it's brought back)
As per the other suggestiong, BRING BACK THE MODAL DIALOG!!! The docked window is STUPID! (Yes command line "TF CHECKIN" works, but oh god, really?)
After that's done, improve the comments text editor to at least be as good as TortoiseSVN: auto-complete and history are REALLY useful features!

PS. And please, oh please, change double-click action on changes files to diff. Just seeing the modified file is not enough!
