I made an updated sandbox theme using different colors and better margins/paddings as the default sandbox settings have ugly link colors and problems with longer project titles. I removed the project and company icons because we felt they only make it more difficult to work with projects. Those can be easily "reactivated" in the CSS.

Perhaps it's useful for someone.

Sorry, no screenshots.

screenshot please

It looks super clean. I like it, but we need to use default theme in order to spot any quirks :)
