This is one tidy looking task manager and synchronises with Todoist. I have mixed feelings about Todoist, but if this isn't a great looking UX which pushes all of Todoist's idioms right into the background, making it that much more palatable for my taste.

Planner is a work in progress, so expect bugs. You can contribute by testing the software, reporting bugs and/or code and throw Alain a couple sheckles for all his hard work.
