Here's a freebie for anyone who wants to make their own -- the Rush Multiball Tracker!
My test parts for this handy little tool have been sitting on my desk for literally six months, so I finally decided to finish it up today.

Back in the early code, there was no way to keep track of what Multiball modes you'd played so far. You need to know, so that you can play all six, working toward Cygnus X-1 Book 1. Eventually, after lots of pleading from owners, the programmers finally added a screen in the Instant Info to tell you which multiball modes you'd played.
With that update, there wasn't much need/desire for my fun little tool, so I never bothered to finish it or put it in my shop.
Personally, I like the idea of not having to pause the game to access the info! So I finished the Multiball Tracker this evening and tried it out -- I really like it!
Start a multiball, close the window, and see at a quick glance which modes still remain.

I've posted this on Thingiverse as a freebie (not for resale). Print and assemble your own!
1) 3D print the housing and six tabs in the color(s) of your choice
2) Print the icon strip on regular paper -- image should be sized to 4.062" in length
3) Glue/adhere the icon strip to a piece of magnet sheet -- the type with an adhesive upper surface will work best!
4) Glue the housing to the magnet/icon sheet combo, using super glue along the edges and the 'beams' between the windows
5) Insert the tabs oriented so the raised piece can be 'dragged' open or closed!
