Startup Idea: Personal Overlay Quick Input Menu for Mturk Users

Startup idea to develop an advanced autofill tool designed for Mturk users. The tool would allow users to create a customizable dropdown menu listing their most commonly typed inputs. The tool should be able to overlay on top of any program and provide quick access to user's saved information.

im not employed outside the home, but do spend 5-7 hours a day here on Mturk. The biggest software need i have is better tools for mturk.

I input the same info time and time again every day. I do have a few basic hotkeys set up, but im not tech savvy enough to create enough of them or keep track of them all.

Ideally, what i would love more than anything would be my own personal drop-down menu, that i could overlay onto any program im running, and choose from a list I create of what info i'd like to input into any given field.

I know, i know, auto-fill can do that. But it can't really predict what I want every time. when i start typing my zip code auto-fill wants to insert 9 digits, not 5. when i want to input "female" autofill has it's own ideas.

I just want a list of about 40-50 most typed things, where i can right-click and have all my choices right there. am I doomed to a life of hotkeys and copy/paste?. i have a few hotkeys, and tried running a few scripts but they're really not as fine tuned as i'd like. there's got to be a better way.
