Joao,
Thanks for the feedback. I am going to ensure that the team reads your comments. What version of jQuery were you using when you had these issues? I know that the selector performance has been improved in v1.1.3 and I know that Brandon has done a ton of work on dimensions. Can you setup a test bed for us to work with?
Too bad is that whenever I try to replace jQuery, I always seem to fail at that, and end up returning to jQuery again. I've tried YUI, Mootools, and I just tried Prototype for the first time.
Then stop trying! You know you love it and you can't get away from it. So just let it happen. It'll go easier on you.
BTW, I don't use the chaining of jQuery much. ;-)
Ha! Your loss! ;) Rey...
