[Feature request] Option to modify app icons and app titles

I really enjoy Bliss as a simlpe and clear launchers. There's just one thing missing. The possibility to modify app icons - as for instance Lawnchair is allowing that. It would be absolutely fine to do this manipulation in the app submenu under settings.

I consider both options as very helpful in order to convince users to start using at least alternative open source apps to access services such as FB or Twitter. It is not very attractive if you have onknown (or too long) names and unknown app icons on your screen to access them.
