The best feature ever put into any program
 

based on my experience today is 'search and replace'. The person that first thought of that is a modern hero.

search and replace with regex is even better. :)

yep. search/replace that will search through sub directories and all .htm and .html files rock. Saves a ton of time when you have to make a minor change on thousands of pages

Yep save TONS of time.

yeah, a ton of time

Which is the best you have used?

I could actulally use one that does that as well.
