I would love to see the ability to move to/from or highlight begin/end braces, tags, keywords, as others have said.
I really like the editor, but there are a few things I wish it would do easily.
* A New Text File (or New Blank/Empty File) command. -- There are many times I need to create a plain text file. I used to use HomeSite for this, and I miss that with CoffeeCup. I find myself creating a new file, then selecting all and deleting it, each time I want an empty plain text file. The same could be used for other file types. -- Is there an easy way to do this, and I'm just dense in not having thought enough?
* I've been trying out new HTML5 and CSS3 and a little SVG lately. The editor's internal preview uses IE, and most new things in CSS3 aren't supported yet by IE. I know that's not CoffeeCup's problem, but is there a way to switch the default internal browser or some other workaround, so I don't keep doing a Preview and then Test view in External browser.
* What about making it easy for us to add in SVG images?
* I won't fuss about CSS3 new, experimental features. I won't. That is too far beyond CoffeeCup's team, or any of us. Aarrgh! :p XD
-- I'm looking forward to the upgrade rumored in recent emails from CoffeeCup.
