Add back outline option to helper panel #7300
Description
Describe the bug
I love marimo for many reasons (vs hex / jupyter), but one of them iswas the ability to have a permanently visible outline on the left hand side, which lets me easily navigate my large notebooks. But in a recent version (somewhere in the 0.17.x series?), support for 'outline' in the helper panel disappeared (with no mention in the release notes) and is only available on hover over (which is ok, but is awkward to use as it is not always visible and has so much less real estate). Sorry to be this guy but can you please put it back?
Thanks in advance!
