Thanks a lot for this! It inspired me to write my own statusline.

Where did you get the rounded circle unicodes, and do you have the exact codes?

I found a pair, but they were smaller. I could use a pair that is a little bit smaller, but i'm guessing that isn't possible

Nice to hear that it inspires you for an own statusline. :)

The characters are in the line 37 and line 38. The unicodes are U+E0B6 for left and U+E0B4 for right. Both characters are in the private use area of Iosevka.

Cheers!
