Fix waste of space of collapsed left panel

[azuenko]

Hello,

I've made a fix to make left panel look more pleasant in collapsed mode. I've tuned some CSS and removed chevron in collapsed mode.

@azuenko Thanks for making this contribution a while back!

It looks quite nice to me, and it may have slipped through the cracks in our review process. 😭 To move forward, I think we'll need to:

• Update the PR or each commit with your sign off as described in CONTRIBUTING.rst
• Fix merge conflicts
• Design review
• Code review

If that sounds good, please take a look a updating the PR to fix conflicts, and then we can move forward from there.

Hello @jryans

I've updated the PR: resolved merge conflicts and added signed-off-by tag. Could you please proceed?

Thanks!

Great, thanks for continuing with this effort! Next step is a design review. @nadonomy, could you provide design feedback on this?

This looks great! (And checked the design review in your comment above).

@jryans I held off from formally approving the PR via GitHub as the code review is outstanding, but just lmk if you'd prefer me to sign it off via GitHub here.

looks good from a code perspective too, thanks!

(a green light in the comments is not much different from a green checkmark tbh)
