IE7 Beta 1 Minor Annoyances In Tabbed Browsing

After futher playing with IE7, I have come accross some other annoyances with Tabbed Browsing.

• Modal Dialog boxes lock the whole of IE7, why can't they just make the tab that launched the dialog box locked out.
• Hovering over the tab doesn't seem to pop a tooltip up, If I have two pages open on the same site, with each site having a long title I can't really work out which of the two tabs has the content I need.
• I would like a quick way to close a tab down
  • a) without having to go to the right of the screen
• b) without having to right click on the tab

I accept the fact that some of these might have good arguments against having them, but I these are things that frustrate me a little whilst using IE7.
