TYPO3 Core

Hello Core Team,

this i just a little question about an improvement of the link wizard in
the rte.

In 4.4 the Link wizard is an ExtJS window -> correct decision in my
opinion. But to get the most (speed) out of it, there should be some
little improvements:

1. make the window modal
2. Make the Tabs real extjs tabs
3. Cache Tree and Filelist or use the new pagetree in 4.5
4. Preload External Link and Emaillink Tab content.
5. conclusion (make the complete wizard in ExtJS ;)

Thanks a lot for your work

Best regards
Kay
