Estimatr: Project Estimation Dashboard UI

Had some extra time this weekend to update an application called ”Estimatr”.
I spent a bunch of time iterating on this dashboard, trying to come up with a design that is intuitive, looks good visually and is 'generic' enough to fit every section. The challenge arises essentially from the different navigation levels: main left menu. I experimented and came up with this.Feel free to share any feedback you would have that could help me.

Press "L" :D
