Doesn't seem to work as advertised in Chrome (dev channel).
Not bad, but I was never able to really get into CSSEdit, which is sort of what I imagine it to be similar to. A lot of missing editor features - or maybe it just not being vim.
My biggest gripe here is that I have to trust someone else to host my CSS. I just can't do that.
I guess I was hoping for a better CssEdit and it wasn't.
Its extra work, but you can publish the exported CSS with your site.
I did read that quote, though.
That said, if you could send us a bug report at webputty@fogcreek.com or via https://webputty.fogbugz.com/?pg=pgPublicEdit we'll take a look and see what we can do.
If you want to host it yourself, you can use WebPutty to edit it, and then use the export link (page with a green arrow coming out of it) to get out the compiled CSS.
