I've been using Suru for a few weeks and I think it fits in pretty well with the other defaults. I made two small tweaks:
- I edited the
Inherits= line to
Ambiant-MATE in the
index.theme file so the fallback icons are the default Ubuntu MATE ones, and
- I removed four icons relating to window close/maximize/restore/minimize because they made the CSD window buttons look different from the non-CSD ones.
No, the folders aren't green, but the colors all fit in since Suru is designed to fit in with Tango and Ubuntu colors.
