[feature]: Way to remove/reorder columns/sections in kanban/list view

Is there an existing issue for this?

• I have searched the existing issues

Summary

Could it be possible to customize the columns on the Kanban view?
Similarly, could the sections and their order be customizable on the List view too?

Why should this be worked on?

I want a workflow in which I have two views:

• A list view which shows all issues (backlog or not). The backlog section is shown last.
• A kanban view which shows all issues which are not on the backlog.

While the kanban view can be achieved by filtering out backlog issues, I notice that the "backlog" column is always there.
For the list view, it seems I can't reorder the sections, and the "backlog" section is always first.
