Sidebar horizontal spacing is too loose
While I generally like new left-sidebar idea it essentially wastes too much horizontal space and looks really badly layout with its too loose spacing.
Comparing to other UI element or even other similar sites (GitHub, Bitbucket) it definitely needs some polish.
I do understand this is consequence of some constraint that icons are centered against top left GitLab fox icon and text are aligned with top Dashboard. But I think this design decision is BAD.
