ttree v0.2.0 Preview mouse input is handed to tmux instead of interpreted by ttree, so clicking a pane, dragging to select and scrolling the scrollback follow your own tmux config. Copies made in the preview are relayed onward as OSC 52. ttree keeps tmux listening for the mouse in the session it mirrors and puts your setting back when it stops, and no longer mirrors the session it is running in. The tree/preview divider adopts your tmux status-bar colour.
