Hi, It would be useful if individual nets could be highlighted. This would make it much easier to understand the logic behind hierarchical sheets, sub sheets and labels etc. This is especially the case for new users of Kicad and general users. Unfortunately I'm not a programmer so I cant help here. I remember using a program called Ulticap, a schematic capture program which was a part of Ultimate's Studio package (now Electronic Workbench). This had the ability to highlight nets and it made understanding connections a lot easier.
