It is already set for 0 spacing, though admittedly I don't see anything wrong the spacing myself doing a side by side, the only issue I notice is that some of the lines between the folders and the plus buttons don't fully connect. Thanks for continuing to support this mod, it's one of my favorites currently. I implemented a option to draw the gradient. It also removes the etched edge drawn around the band. I've also implemented a themed frame for the X button, but wasn't able to test it myself. Please test: {code}// ==WindhawkMod==

# Classic Explorer Treeview
This mod changes the Explorer Treeview (otherwise known as Folder Pane or
Navigation Pane) to look more classic. It draws it's own Folder Band with a
functional X button. If you are using OpenShell, then you need to set the
correct settings for Classic Explorer in the Navigation Pane tab: Vista style
and Tree item spacing 0.
This mod supports the Classic and Basic (non DWM) themes, others may work but
aren't supported.
If the mod is to be disabled, it's recommended not to use file explorer windows that
were opened prior to disabling it, as it may lead to undefined behaviour.
For issue reports, contact waldemar3194 on Discord, or file a report at my [github repository](https://github.com/CyprinusCarpio/windhawk-mods).

the folder band
- Draw bottom rebar line on the folder band (Cynosphere)
- Add option to use highlight color for drawing lines for better visibility on
dark themes (Cynosphere)
## 0.2
