Feature to save workspace layouts so it doesn't reset every time the app is opened on PC startup. It would really help having a music based layout while sketching, a more techy white-noise or lofi based layout when coding, and a more "busy background" noise like an office or city with a heavy notes based layout for writing up reports or documentation. We could arrange and name these ourselves and have a quick swap button/dropdown for changing between them. Sound settings should also be unique to each layout. On a busy city background one, i may want the city background sounds at around 30% and the keyboard typing sound at around 80% so it comes through over the background. But for the lo-fi one i would want the lofi music to come through above the other mixed white noise sounds.

Maybe 3 layouts on free tier and up to 10 on paid tier?
