Sections in a board cannot be moved freely. Please allow a drag & drop movement of the sections inside a column and between different columns. It is crucial to be able to make my own ordering on a board.
Similarly, please do not automatically sort board groups alphabetically. Allow a custom ordering by drag and drop there as well. You already allow boards to be custom-ordered via drag and drop, so it should be easy to extend. Allow top-level boards without a group and board groups to be mixed in the ordering.
Sections can be re-arranged using the “Rearrange Sections” menu item in the Board edit menu.
Will investigate the effort required to allow the reordering of board groups.
Please allow drag and drop between all boards.
