Could you please implement a small tray icon to display some information?
The information I'm thinking about is:
- Next flush will occur in xx minutes (when defer write is active)
- Whether FC is currently flushing (if defer write is active)
- Which amount of the cache is in use (and for what? like 60% are used for read cache, 30% are used for defer write cache and 10% are not used at all)
A button to force a "flush" would be great too

(Without having to open the normal application every time)
Thank you for your consideration.
