i was bothered by the complexity and long load times of the iphone views - they look great, but even on wifi they took a while. what began as a hack to modify indigo's default mini pages, soon evolved into a plugin thanks to the efforts of jashaffner.
please see:

to get the most out of these replacement files you will need experience with indigo, zip files, and possibly html and terminal. i'll do my best to answer your questions and give support for these replacements, however, the boards here are a great resource for anything that goes unanswered.
please feel free to contribute. i don't have a sprinkler system, so i'm not sure how these views look for those who do. post snapshots, if you like!
