Measuring/Repositining of the board
When pinning the tools on the left of the board, it will stay on top of any columns that are collapsed there. It would be ideal if the board shift a bit to the right so all the content is displayed.
Also, when collapsing columns, the width of the page will not shrink. Even if all expanded columns can be accommodated in the visible width, there horizontal scrollbar will still be displayed and the window can still be scrolled. It would be ideal if the window resized and no scrollbar was shown because when dragging tickets the window scrolls accidently and sometimes the ticket is dropped in the wrong column.
We understand your requirement and add these feature request in the product backlog.
