I have to agree with everyone that there’s no way around mentioning “arrangements” explicitly… also, “objects” does sound a little programmer-ish. 😉
Brings me to a question: what do you use the “new sound” menu entry for, anyways? It doesn’t seem possible to record or do anything else besides drawing waveforms in the stand-alone sound editor.
If it were me, I’d choose some variation of “Plugins and I/O Devices” (or mappings) for the other panel.
