Quickest way to bring in a Google Doc directly to a task?

I see there are lots of ways to bring in G-docs. I can go to the documents section and add them, or I can go into a project's documents section. I also see how I can "move" (why isn't that function labeled "link," just saying) a document to a task, where I ultimately want it to be associated.

Is there no way to select a task row and use some pulldown to add and connect a document in one fell swoop? Or a + button somewhere?

Also, is there a way to have a button in a task row to take you to the task's documents? I see the status icon field, but those things are so small ... if you don't click really carefully, you go to Updates. Can that field be customized? Or is there another column field I should use?
