I just pushed an update for the preview program that properly shows if a rain delay is preventing a program from running (red and struck out). Figure with all the emphasis on automatic rain delay, I should emphasize rain delay information everywhere.
I enabled master station on the program preview page as well.
Update: I added the program coloring scheme that Ray employes in his program preview. Almost the exact same colors too (minor tweaks for the ones that clashed). I think this brings the program preview all the features Ray’s includes!
