A row click slides the pane in as a fixed-width drawer: the toolbar's
calls to action leave first, the pane is laid out before its first open,
and a model switch fades one out and the next in. The model information
dialog folds into the pane's information tab, and a chat started from
the pane closes the manager and focuses the composer.
