* Allow mounting arbitrary columns * Refactor column headers, allow pinning/unpinning and moving columns around * Collapse animation * Re-introduce scroll to top * Save column settings properly, do not display pin options in single-column view, do not display collapse icon if there is nothing to collapse * Fix one instance of public timeline being closed closing the stream Fix back buttons inconsistently sending you back to / even if history exists * Getting started displays links to columns that are not mounted
