In hindsight, it looks like my quest to tweak how Emacs looks and feels is to make it more Mac-like. No wonder, because I really like the OS X-era UI. So I’m still using the system default selection highlight colors and want these everywhere.

For example in neotree.

The hl-line current line highlight, combined with lin.el (which I use for half a year) to make it act as a prominent selection instead of a subtle hint in that mode, did lose over neotree’s own face settings.

Inspecting why that looked the way it looked via C-u C-x = to see the character and face information, I got this:

There are 2 overlays here:
 From 565 to 598
  face                 hl-line
  priority             -50
  window               nil
 From 578 to 597
  button               [Show]
  category             default-button
  face                 neo-file-link-face
  follow-link          t
  help-echo            [Show]
  keymap               [Show]
  neo-full-path        [Show]

Never saw this before, but “priority: -50” sounded like the way to go. Raise the priority, then maybe the hl-line face would override the neo-file-link-face of the file “button” at point.

But there’s no face property called ‘priority’. Searching the web for this, I found out about show-paren-priority on Emacs.StackExchange, so it looks like this is commonly a variable, and yes, there is a hl-line-overlay-priority and its value is -50. I don’t know what other priorities there are, so I’m just flipping it to +50 for good measure.

(setq hl-line-overlay-priority +50)

Disable and re-enable hl-line-mode and then it looks good!

The next nit I want to pick is to enable horizontal scrolling with the mouse for long filenames, and removing the block cursor when LIN is active (which you don’t see on the screenshots because I timed the picture with its blinking).
