When I do web developing again, I might need to consider Xyle Scope. It seems to be the best CSS editor I have seen until today. It has Safari (or better a WebKit view) embedded and offers quite some more stuff than simple on the fly editing.
And what is really cool about the evaluation period (well this tool costs money, yes) is that you have 10 days, but only those days that you really work with the tool decrease your testing period, very nice!
I have tried it now and I am impressed, especially about the way you can select and edit the tags/style you want. But one thing really cost me time, to find out how to apply the changes I was making to the CSS. I thought (Mac OS X like) that changing the value would do it, so I changed a value and pressed TAB. Nothing happened :-(. May be there is some setting or alike. Long story short, simply press ENTER. grrr….
But great anyway, I will buy it when I develop web stuff again, for sure! And it’s from Germany
