I have a "Most Visited" link at the far left of the browser toolbar, mso.
It's "recent pages" on the 3.6 version I've reverted to, JPB. Couldn't find the equivelent on the 4.0 version & it was driving me nuts!
(say nothing of confusing Butrflynet, who couldn't figure out what I was talking about!)
Useful reading your input on 4.0, Cyclo.
No doubt at some point I'll have to have another go at it & the information you've posted will definitely help. (I hope!)
