[REQ] read/write access indicator

[Fred Doolie]

Is there an app that displays some kind of indicator for read/write flash access? You know; something like the little light on a hard drive. I'm never sure when it's safe to soft-boot or turn off my phone. I don't want to do it in the middle of a write operation and bunk my flash memory or important data. Something that displays red (writing), green (reading) and yellow (no operation) would be perfect.

Thanks
