My suggestion for both the banner and possibly the synthetic channels would be to allow the use of the custom functions that can already be used for website variables. For instance I would like to add the daily snow total to my banner but currently this is not an options. If I could either define the synthetic channel with the function 'STAT:SNOW:TOTAL:TODAY' or just call that function directly from the banner it would solve the problem and give more flexibility.
Curious what others think.
