Add a dock to floating workspaces
Reset empty workspaces to a new default layout, and call dwindle tiling (#15266)
Change no saved layouts when the workspaces cannot be read (#15267)
Turn titlebars on when a workspace starts floating, not on the next reload (#15271)
Update omarchy-hyprland-titlebars to 0.2.2 (#1016)

dhh proposed and merged omacom/omarchy#15263 into the quattro development branch on October 13. It adds a dock for finding pinned and running apps on floating workspaces, with an app grid, drag ordering and auto-hide. Super + M minimizes a floating window, and the dock restores it. The current PR description also explains how custom web app launchers retain the identity needed to appear in the dock.

Related quattro commits make empty workspaces adopt a changed default layout while preserving occupied workspaces, and prevent an unreadable workspace list from erasing saved layouts: omacom/omarchy@b6af62e285a3 and omacom/omarchy@ed92b0753f95. Another enables titlebars when floating mode starts. The package repository's master branch also received titlebars 0.2.2, adding resizing above a floating window's titlebar, in omacom/omarchy-pkgs@eba2a95f2e9e. These commits are attributed to David Heinemeier Hansson; they do not establish a stable Omarchy release.
