Replace Tigra with other menu system

I like to suggest in future version of hobbit to replace Tigra with other 
java script menu system like YUI.
This is my personal opinion, YUI has more to offer in term of menu 
capabilities while Tigra is free only on   basic menu fuctions.

I like to hear Henrik's and others  comment on this subject.
