I'll look into it for a future version, but it will only build-in if it works on all browsers (desktop and mobile) and doesn't break other events (like scrolling on mobile devices, which is tricky even with a normal click). Double click has always been some kind of hack. Personaly, I prefer buttons because they do not require any explanation, while a double click is a 'ghost' functionality that needs to be explained to the user. It is not common in WebApps.
