Hi Danny, I've thought some about that before.

One problem is that it is possible for there to be a "mixed" state where only some of the items for that slot are selected but not all.

For example if you have 5 spheres that have style = Default, and now you go and select 3 of those spheres with 2 still deselected, what should the Default style indicate in that case?

Also putting a big highlight like you show there does seem kind of a bit "in your face".

So those are a couple of the UI design issues which need to be resolved before this would work.

One thing I've thought about a bit is maybe having a small yellow bar on one side of an item to indicate selection, and it could have a half bar for the mixed state. I have not really fully explored that yet though, but something like this maybe:



But I'm not sure if that is distinct enough or not.


Let me know if you have any ideas about how to show the mixed selection state in a good way.
