I find the Pool Math logs are especially useful such as Add a Note, Track expenses and perform maintenance in addition to the test results. Currently I "add a note" when I add water to my pool due to evaporation in the hot summer months. It would be nice to add that feature in Perform Maintenance section - it currently has backwash, clean filter, brush walls and vacuum. Add a 5 item for "adding water". It would need to have option to either add "inches" or via "amount of time". it is unlikely anyone has a volume flowmeter on their fill line (at least I do not) but I do watch how many inches I add (monitor in the skimmer) or just set my alarm for a time - i.e. 45 minutes. I currently add this info as a NOTE but would be nice to have it as part of the maintenance section. Thanks.
