aedile,

I have already addressed this with the new DMX-3000, if you are using the variables in more than just a couple places, (ex, I use the slider on every movie details page) the amount of space you save by using 4 variables instead 16 is no where near the extra space you will use up by making your macros smart enough to check 4 variables each time instead of just 1.

In other words, instead of having a single line in the macro that checks 'v15=1' you will need 4 lines in 4 different macros that check 'v0=1', 'v1=1', 'v2=1', and 'v3=1'

Variables in the remote take up very little space, extra buttons to accomodate more macro lines however take substantially more space.

I commend you on your calculator though, now I want to see it multiply and divide. That binary math is always fun :) Let me know if you want any more info on this.
