Hi Danny, definitely want to do that at some point - it will definitely be a really natural fit for that pop up panel to have that.

It's just not quite as easy as it would seem at first - even though that thing looks like a calculator it isn't really a calculator framework yet. That needs some additional logic for sequence of operations, etc... it's not just a matter of literally only adding in a button.

I was kind of thinking of keeping the panel pretty small by default with just the numbers and then have some kind of expander widget that would widen it or something to open up calculator functions.

Not quite sure when that will happen yet. It's actually already on the wishlist for keeping track of it.
