Just as tracks and buses are distinguished by a color band if they are MIDI or audio, the pseudo-plugins should also use this color setting in the options. This way, not only could you easily distinguish whether the insert is MIDI or audio, but you could also differentiate the pseudo-plugins (sends) from the rest of the plugins (signal processing or synth).
The only drawback I see is ensuring the text remains legible.
The first one works perfectly.
I'll try to explain the second one better.
