I currently use Zend Studio 5.5 at work which is overall alright, except that it crashes on me and can really slow down (stupid java! ) One thing I REALLY like about it that I have not found in another IDE is I can CTRL+CLICK and it will automatically open the file and go to the declaration - of the function, class, etc. I've recently tried phpDesigner but it seems to crash every time I close it and it has a similar jump to declaration except it pops up a list for you to choose from which is annoying and a slowdown. Can anyone recommend a good IDE that has good syntax highlighting, easy project file navigation, [maybe] SVN integration, and also does a good job of code-completing/highlighting of HTML, CSS and JS? Thanks to all suggestions!
