One feature that seems to be missing in all of these playground is search. I am not talking about searching inside a script. I am talking about searching through my entire fiddles to find some scripts I worked on 3 days ago, 5 months ago, 1 year ago, 10 years ago. I have a lot of fiddles in jsfiddle, but it is really really hard for me to dig out something I used to have worked on. Currently the only option is to eyeball the entire list page after page and see if I am lucky. I tried google searching my fiddles as well, nothing turns out.
