I was just playing around with Dremweaver CS 4 and noticed a nice feature:
When you select a folder in the File Explorer and then open the Find&Replace-Dialog, then that marked folder is filled in the Search-Dialog as the starting point for that specific search. I think that's a great idea, as you can select a folder with a single click and no need to click through a file dialog, as it is now in WB.
I think that would be a great thing for WB!
