I think we need to add support for buses some day

All schematic capture tools that I have ever used support homogeneous and some even support heterogeneous bus-symbols that let you do huge designs. Kicad is going to add support for heterogeneous buses either in V5 or V6. If librePCB wants to be taken seriously as a tool then you should support both types of buses.
