Re: About the F18 spin and how to solve issues.
elementary-xfce works properly.
If size isn't an issue (and it isn't that big anyway) I would replace
'Rodent' for it in xfce4-icon-theme.
I found a couple of issues with application icons (dark
'symbolic'-like icons on a dark menu theme) but it's actively
maintained so it's just a matter of reporting a bug.
