I've been doing some web development recently and tested out a few specific web editors, including WeBuilder. This has a couple of features I found useful - one of which I've already requested: real-time Web Preview update (or preferably coonfigurable to update every x seconds).

The other thing WeBuilder does is to highlight the start and end tag of the current block you are in in a light green colour, and if one of them is missing it will highlight that tag in light red. This is useful as a quick visual indicator that tags are matched.

It would be nice if this was configurable, so that text/regex start/end pairs could be added to a list.

I know EmEditor supports Zen Coding, so not sure if this could somehow be added through that ?
