Two things I found out:

1. The loading mask sucks, especiall, when loading list module with many 
tables (This is already tackled by the extension mentioned).

2. There is a delay of 400 milli seconds after each click on a page in 
the pagetree, to be able to detect a double click (to change the page 
title). This is almost half a second where nothing! happens.
After changing this value (in 
t3lib/js/extjs/pagetree/javascript/tree.js) to 0, I was not able to edit 
titles any more, but the loading the content frame went a lot snappier.
Probably there is a better solution for detecting a double click.

Kind regards,
Helmut
