In a narrow or docked window the open list now sits against the rail over a
dimmed page, and closes when a folder or character is picked, when the dimmed
page is pressed (that press does not reach the cards) or on Esc. Wide windows
are unchanged.
The activity log also drops its oldest entries past 2 MB, so long canvas
entries cannot outgrow the JSON writer's limit and stop the log.
