@danitrusca I had a similar feature request at Give the center node of the local graph a distinct color - #3 by JonathanBuchh
In my post, I proposed to give the center node a different color by enhancing the Group filter. I think this proposal can be a good supplement for the 2nd solution you proposed.
I think we are asking for the same feature, may be the two feature requests can be merged into one, so that the attention can be focused and this feature may have a greater chance to be implemented.
What do you say?
