I love the search change, I thought something looked off when switching between neovim and helix. What if we meet in the middle for the whitespace, maybe highlight_high? Seeing how this is an opt-in feature, more contrast via muted is fine if you feel it's needed :)

You are right, the highlight_high is better, since these are way less important than comments and shouldn’t be with the same colors.

As for the search, happy that you like it! Now that I used it a little, I’m thinking of maybe adding an indicator of which line the cursor is on, because it becomes tiresome to always look at the left side to know which result is selected. Especially with long paths spanning half the editor.

What kind of highlight would in you opinion be better suited here? The default theme changes the foreground but other themes appear to be fiddling with the background.

For the current search line background we use overlay in other apps :)

Okay, added the ovelay. It should be good now!
