In SP6 one had the most used websites directly available when right clicking the SP icon.
The actual amount of available QA entries could be set in SP6 settings.
In SP7 beta if you click the icon there is a QA tab at the left, actualy the top and starting tab, but there's nothing comming in it and also you don't find a possibility to set the amount in settings.
In SP7 you van find the Quick Launch if you right click the icon, but I like the old way more.
Although this method of Quick Launch could be interesting to, but then it shoudl work faster then it does now.
It works so slow while typing the characters of the link you want to look for.
I would like to suggest to use both Quick Launch and Quick Access if it is not an error that the Quick Access is not working.
In SP6 I cannot remember if there was a Quick Launch, I always used the Quick Access, and then set to 10 entries, which was enough for me.
