Feels like a project covering some of the same ground as task warrior [0], which I've used on and off over the years. The main thing I've appreciated is integration with various tools - I had access in both vimwiki and the macOS task bar for a while which was nice - but all these tools miss the key thing that stops me using them all the time: integration with tools on my phone. It's great having cli access to tasks and in other places, but without ubiquity, given the way I work, it might well just be another place that ideas of tasks I need to do go to die.

Looks great but a configurable date format to support the European standards of dd/MM/yyy would turn it into something I could actualy use

Does it handle both recurring events and recurrence?

E.g. move the lawn every other week vs pay rent on the 17th every month. If I go a week overdue on rent I still need to pay the next on the 17th. If I go a week overdue on the lawn I don't need to mow again for two weeks, not one.
