Use case or problem
Nodes in Graph view are colored using different tags. Right now, a node can only have one color, even though there are multiple tags with different colors assigned to it.
Proposed solution
Add a feature which alows a node to have up to 4 colors like in a pie chart, so you can clearly see its assignment of multiple tags when zoomed in. When zoomed-out, make it the first mentioned tag color, since the 4 colors won’t be visible clearly at one point.
