Channels are fine as far as they go, but they require that I set them up in advance of using them. I am using Channels to group my activity by type. What I want in addition to Channels is the ability to add a label dynamically to the task in the same way that I can in Todoist. As I work with a new client or on a new project, I want to be able to add that label to the task without having to go to a maintenance screen to create the new label.
