I have a couple of questions about displaying data on MMW. When viewing a Mayfly site, can the display sequence of its variables be re-ordered, or is that fixed, based on the order in which you define the sensors and measured variables for the site? Second, I assume that if you delete and then re-add a measured variable, a new UUID gets generated. So if you make any changes to variables after programming the Mayfly (with UUIDs, etc.), the linkage between the variable in the Mayfly sketch and the variable displayed on MMW will potentially get broken. Is that correct?
