Well that's the point: one shouldn't have to do up worksheets first, especially if all one needs to change is one or two options. If I enter a bitmapped location that affects options A, B, C and D, and all I want to do is change the behaviour of option C, I still have to make sure I have the rest of the entry correct for the other locations, lest I break something else. That's just silly. I should be able to enter installer mode, select the location for the *one* option I want to change, enter said change, and be done.
I came from a (limited) programming background as well. 6502/6510 assembler, BASIC, some machine code...
That type of programming is just fine... if you're living in 1983. Or, I guess, if your panel is using 1983 technology.
