I would like to request a very simple feature: a "pause" button on the replay gain scanner window.
This would be useful on laptop computers. (The problem is not the high CPU usage (if we forget about overheating), but the constant hard-drive access with slow laptop hard-drives.)
Request noted, possibly to be added after 0.9.5.

Also useful in case you have to pack up and go elsewhere while in the middle of a scan of a large collection. It took me 3 hours to scan the 6600 files (56GB) on my laptop the other day, and halfway through a scan I had to pack up and leave. I then had to start over the next day.
You could have used laptop's standby mode instead.

It would also be nice to be able to just scan files that don't have ReplayGain info. Unless there's a way to look this info up that I'm not aware of yet (I'm new to Foobar2000, and this latest version finally converted me!).
It already scans only files that don't have ReplayGain info.
