I've been a Wunderlist user for a while, now shopping around for a viable alternative. It's truly amazing how few options there are that match Wunderlist's feature set. It's also truly amazing how "basic" the features I'm looking for should are this day and age, yet there are very few solutions. I don't want a taskwarrior-esque system, although it would meet most/all of my needs, as I share lists with family memebers who are not tech-savvy in the least bit. Of course, this screams side project.
