Hard coding a color is a terrible idea. Ina a dark theme, you would get light text against a light background. This has to be tied to the theme colors to work.
I also wouldn't space your code into columns like you are doing a few places right here. Just use normal spacing.

Same here. Don't space things this way just so they line up. It's fine for the function arguments, but not really here.

Summary
This PR adds two new features to the Nemo list view:
1. Custom Date Format
A new "Custom…" option in the date format dropdown under
Edit → Preferences → Display.
When selected, a text field appears where the user can enter a
format string using the following tokens:
Example:
YYYY.MM.DD HH:mm→2026.03.21 14:35Changes apply immediately without restarting Nemo.
Two additional buttons allow managing date column widths:
2. Alternating Row Colors
A new checkbox "Alternating row colors (white / light gray)" under
Edit → Preferences → Views → List View Defaults.
When enabled, odd rows are displayed with a light gray background (
#ebebeb) and even rows with the default background. This improves readability in long file lists.Enabled by default.
Implementation note: CSS
nth-childselectors are not reliable forGtkTreeViewrows in GTK3 (row nodes are recycled dynamically). The alternating background is therefore implemented viaGtkCellRenderer::cell-backgroundusing cell data functions, which is the only robust approach in GTK3.Changed files
