Lenses preferences are erased when a new session is started

[Danillo]

The dash saves its maximized/non-maximized state between sessions. However, lenses preferences (e.g. expanded results and results filter views) are lost when the session ends, so the user has to keep selecting these options after each new session.

Though the search field really should be reset, the "see more results" and "filter results" preferences state (shown or hidden), like the dash maximized/non-maximized state, should be saved between sessions.
