What would be handy for me, is a single screen/page that kept track of my SWG and my IpH, like:
March 1: Set SWG to 35%, runtime to 4 hrs
May 15: Set SWG to 50%, runtime to 6 hrs
July 5: Set SWG to 60%, runtime to 8 hrs
August 1: Set SWG to 40%, runtime to 8 hrs
October 30: Set SWG to 0%, runtime to 3 hrs
Something similar for IntellipH. Include % dilution of acid.
Something similar for Stenners, and other types of auto dispensers...
Etc.
The interface could be fairly simple, maybe a dozen or so sets of fields. Maybe the ability to add pages, if someone needed to track year-after-year history?
Instead of having to hunt down notes, in a very long log, and only be able to see them one at a time.
