Blender 2.8 is being shipped with vectorized monochromatic icons, which means it won’t pixelated in the zoomed view, it is a benefit for high-resolution displays.
Keeping things organized is key when it comes to working on a large project.
I was working with another Animation package on a big project that had many assets. All the assets where created according to the physical scale and built. The project had many scenes, I started organizing it by naming mesh and grouping them for easier selection and to have a better workflow.
