It would be nice if the Global JS/CSS sections of the Optimizely editor were code syntax highlighted and supported code editing functions just like the Variation Code box does!
I already suggested this to the support via email, but i think its okay to rate this idea here, too.
One have to know, that this is a pro idea only, most of the people will not see this as a problem, but if you have to edit a lot of css or js for the experiment, it's really a pain to use the current solution.
I would improve this idea with a larger code input, the current version shows 7 lines of code only. I know I can increase the textarea with the resize handle, but that's a temporarely solution.
Ha, I remember when I suggested this to James. This is really a no-brainer. Hope to see this feature soon.
