Horizon View: Have a right-sidebar in Timeline view

First of all, I love the app, it is excellent. I just have one feature request.

When I am adding tasks to the week or month view, I am not necessarily thinking about when I will execute each specific task. Then, on weekends, I sit down to plan all the tasks on my calendar. I really appreciate what you have done with the different views that allow us to record tasks for this week, month, or year. It would be great to have a two-column layout or a sidebar that allows us to drag and drop tasks between different views.

For example, in the timeline view, it would be helpful to have a right sidebar that allows me to select any task from the week view and place it directly on my timeline.

Similarly, a two-column layout would be useful, where I could drag tasks from the month view into the week view for more detailed planning.
