Main Menu UI: Reorganize Tabs

The ability to reorganize the order of Tabs. (like Tabs in modern browsers)
tabs

And please also add Ctrl+Tab, and Ctrl+Shift+Tab (and Ctrl+PgUp, Ctrl+PgDn) move between tabs. Would be great to be able to do this quickly via key commands. Also, if there is a keyboard shortcut that can close the tab without the save dialog, that would be very useful too (to macro, and use).
