Good, but could be better

I find this app very convenient, because I check Facebook regularly.
But I dont want to use this app while Im not chrging my MacBook Pro, because it takes a lot of CPU and RAM.
The battery life is at least 1 hour 30 minutes shorter if I have this app open at all time.
Please improve the cpu and the ram usage of this app :).
Other than that, I think that this app is perfect!!
