Hey, there. It'd be nice if the gray stereo level meter could be colored the color of the module. Then subsequent effect modules could have the bars be colored according to how much of the signal is coming from each module (i.e. you could see 20% of the level is from the drums, 10% is from the lead synth, etc). It'd be a really unique way to mix and visualize the song flow.
Also, it'd be nice if zooming into modules showed more information, like a miniature spectragraph.
EDIT: Oh, and if this is implemented, then a key shortcut to zoom to a module to show this information would be cool.
