According to https://docs.google.com/presentation/d/16M1BJ2i0AVVgjIAIg0uy2tj0uRDwGhH6jidhBxYl3uk/edit#slide=id.g1a294527ce_0_14 "visual signals" are hard to interpret.

In order to improve / fix this I would like to hear or see some proposal on how they should actually look so that they are easier to interpret. To me they are clear, but that's probably because I am long-term user of Huggle.
