I used to use this almost daily but it was one of those things I begrudged. It's like 90% there but the final few bugs that need fixing make it infuriating to use. For instance, after you save your work, you need to "override and edit" each CSS file in order to work in CSSEdit again. It's very much like closing and reopening CSSEdit after every save, which makes for an awkward workflow.

The developer hasn't released any updates since 2007 (shortly after my purchase) and doesn't respond to emails. I waited two months after emailing before posting this.

Frankly, I don't like the idea of someone who will take money then drop support for the product. S/he should start providing updates, make the code open source or give refunds.

Unfortunately, I have recommended CSSEdit in the past to people who bought it but I can't any longer and now suggest a text editor, like TextMate, which is what I use now.
