I'm a long-time user of IllumSoft's ListPro. It was good because each file had a master list of the lists it contained, and each list was able to nest as deeply as needed. The software enabled you to check-off items (& then either auto-hide them or leave them visible but checked) as you completed them. List could be manually or auto-prioritized. Items could have different colors assigned to them. It was simple in that it was not integrated with the calendar, so no "due by" was displayed on the calendar, tho you could have a date field in the list, & could sort the list by the date field. It was, quite simply, an exquisite LIST program, & nothing more. Is there an Android equivalent? Or, do those which do integrate to the calendar & such also have the list capabilities I've mentioned? I've looked at the other threads regarding to-do lists, and they are fairly old, in technology advancement terms. So, what's the verdict?
