Even the previous Skype had quirks that bugged me. A really simple one was the login screen; after entering your login ID, pressing Tab took you NOT to the password field, but to a little web link thing in between the two fields. So, the one UI element you must use every time you run the program, wasn't thought-through; it's as if they didn't expect that the next thing you'd want to type after your ID would be the password. So every time, I had to hit Tab twice.
