PseudoKanban View

in view options you can add sort by ground color. It is a vertical Kanban view,

This is something that’s probably too far out of the main scope of Agenda, we would suggest a dedicated tool and create links between the two apps using Agenda links.

Are there any suggestions for such an app?

I don’t use one myself but perhaps others can chime in with the tools they use.

MindNode has oneway links to Reminders (other than the check box, which is two way).

It can replicate Kanban. Haven’t tried to do a thing with a three way connection; I just know MindNode writes over Reminders notes data.

And mentioned elsewhere, there is GoodTask. Haven’t spent much time with it so…???
