When building a new Timelion expression, the docs are very useful. But the docs immediately disappear once you start entering parameters for a given function. They should stay active.

Example:

I type ".es", the docs show me what all the different parameters are. (this is perfect/good/useful)

Once I add the "(" to start adding parameters (so I now have ".es(" in the compose window, the docs go away. They shouldn't. I'd rather not have to memorize everything before I use the opening paran.
