I spent a lot of time with that plugin. I thought the changes were embedded in the SQB file. When I moved the VRS installation to another PC, preserving the database, all my ‘work’ was gone. It reverted to standard silhouettes, banners, etc. Unless I missed something, it’s not what I’m looking for.
I saw mentions of Modes2mixer in my Google searches. I was playing with acarsdeco2 and modesdeco2 this past weekend, and saw this file on the same webpage I downloaded the other two.
Not specifically for ADS-B, but with good reviews, is Spot2Log. I’ll download the demo version for a spin.
