Navigation redesign

What this post added

This post details the initial stages of GitLab's UI navigation redesign, focusing on addressing confusion caused by the previous hierarchical navigation and the dynamic nature of the left sidebar. It describes an initial concept that was rolled back due to negative user feedback and then introduces a new approach that separates global navigation (dark left sidebar) from contextual navigation (top header). The post highlights the positive reception of this new approach for profile and group pages and previews its application to project pages in GitLab 8.9, along with mobile improvements.
