Want to use unique font awesome icons

Hi,

there are different font awesome icons for the same functionality in the toolbar, in the notification module and in conversation kit.

Can u tell me the most easiest way to unify these?

Guess it is the best to change the icons in the toolbar to the others.
I know how to use different font awesome icons just need to know where I can change them in the toolbar.

Tnx for your help,
