Love the idea for the track marker notes. Not sure I know what you mean by it though? Do you mean if you put an empty item on the track with text in it then it will show here? Or is it related to your marker/note script?
I would love if it showed the track notes from the SWS note window but maybe that's what you mean anyway?
Also, That's fantastic that you managed to get the reduction meter from the general dynamics plugin. Love that plugin already!
I'm guessing for the RMS and EBU it will need to have the same plugin on the track that was used for the loudness meters script?
