Collapse empty columns in Issue Boards
Description
An illustration is always better that lot of description
As you can see, the "Easy Pick" column is empty. For my team, "Easy Pick" means "It's easy to do it, start working on it before fetching issue from the backlog".
This column will be regularly empty, but it take some places on the screen and not anybody have 8k resolution screen.
Proposal
When a column is empty, collapse it like it's done for "Backlog" and "Closed". It will show only the title and issue count (0 for this case).
Optionally, we may add the possibility to collapse any column we want by clicking on it.
