Auto-Close the left-side-panel

The idea is:

The side-panel always opens on reload, and I always want it to stay closed to give me more horizontal space to work with
Maybe add a toggle to the settings page to choose to keep it closed by default.

Benefit: Helps get rid of a necessary click each time I open a workflow, or reload the page

Yes, it would be great. I am also missing this functionality.
Maybe the best would be, if the last state would be stored somewhere, like in a cookie.

Honestly, I would just keep it closed all the time.
