I've always preferred Wunderlist over Todoist, but this could change things.
I really wish the Wunderlist team would respond to this request. The whole world of Kanban/Agile has really taken off and the ability to switch between lists and a kanban board would be fabulous.
Wunderlist has a beautiful polished app across the spectrum of mobile and desktop platforms. That's something Trello has rabidly avoided on the desktop for various and IMHO lazy reasons.
I think Wunderlist could really benefit themselves and their customers if they’d enchance their product in this manner
Old Post but very relevant. http://davidseah.com/2012/08/goodbye-wunderlist-hello-trello/
A column view would make sense to have as an option and it wouldn't fundamentally change the way the app works. It's just a "list overview" mode. Wunderlist is better than Trello in EVERY way aside from Kanban. It also makes good business sense to create a competitive answer to Trello without compromising your current user base.
I'm in full agreement with the other comments on here. That being said, I'd love to support 6Wunderkinder with a little dough especially if a cheaper single-user pro price was available. The backgrounds, file uploads, the little gold "pro" coin are all pro features that I would pay a cheaper yearly or monthly rate for. $2-3 a month perhaps?
