I agree that this is a real annoying issue. Mostly it is probably an "it seemed like a good thing at the time" type thing without foreseeing the issues that would be created by a features limitations. The quick fix would be to make the only variable box available for these types of variables a text box by default. Groundspeak should consider losing the multiline variable boxes in order to simplify future categories.
The problem here is that it doesn't address the problem completely. If I go back and change my address variable to a text box do I lose the work that previous waymarkers have done by eliminating a variable style and using a different one?
silverquill:
I created a few of my early categories with WAY too many variables
Me too.

I have one that is even redundant. I have a variable in my first category that is not optional and replicates the title of the waymark.

I'll drop into that cat and eliminate that variable to see if I lose the data there since it is redundant anyhow. Vital info will not be lost and I can answer my own question above about changes in variables.
Edit to add
OOOH tread lightly when fiddling with the variables. When I went in and edited the variable I mentioned here it gave me the option to delete the variable. When you do this the previous information is deleted as well. Poof....gone
I still don't know if a slightly altered variable say from an hours variable to a text box would result in lost info but now I am to scared to try. My first attempt eliminated all previous redundant info for the 484 waymarks in that particular category.
