Better usage of the user agent data

Originally poste don github:

don’t think this is a real FR maybe more an improvment

For each activity containing a user agent, should be real good to help the user to understand it

For example you can reading this webpage

to know how to decrypt better the user agent

I know there’s no standard but implementing Chrome FF Safari Edge Opera ones would covers most of the use cases
