Assegnate 5 su 5 stelle

Chris, this is a WONDERFUL extension. It saves me so much time on a daily basis. However, the yellow icon in my toolbar stands out like a sore thumb and distracts me. How can I change it to gray? Can you add a "gray icon" option via a new preferences setting? THANK YOU!

Questa recensione riguarda una versione precedente (1.3) del componente aggiuntivo. 

Thanks for a great review.
I am planning to combine my both add-ons, "Folder Filters Button" and "Message Filters Button" into one add-on in the next version.
I will try to add settings option with perhaps few different colours of icons.

Chris
