Board view
Columns by status or any grouping, with drag to change.
The board shows a list as columns. Switch to it with the view switch in the list's toolbar; the address gets view=board.
Columns follow the groupingLink to this section
The board's columns are whatever the list is grouped by. Grouped by status, you get a column per status. Change Group to priority, assignee, type or anything else and the columns change with it. See Filters, grouping and sorting.
Drag a card to change itLink to this section
Drag a card to another column and Suru Me writes the new value straight away: drop it in Done to close it, or in someone's column to assign it to them. The card moves at once. If YouTrack refuses the change, the card goes back and a message says what didn't save.
Everything else still worksLink to this section
Search, filters, sort and Show closed apply to the board just as they do to the list. Click a card to open it in the issue panel. Each card shows the task's type icon and name.
To make the board your default for every list, pick it under list defaults in Settings.
