As I understand it tags are case insensitive.
This is a bit annoying because I would like to rely on them as an implicit test for, lets say, naming of buttons, for instance.
Someone had spelt an OK button 'Ok' rather than 'OK'. Sure enough the tag for the button was 'Ok'. When the spelling was corrected a test which clicked that button still passed without me having to correct the tag. Damn.
My question is, is there any way to make tags case sensitive, and why aren't they by default?
