Could you please do the same for any other fonteawesome links? like the ones in tags for example, there might be others.

I would suggest creating a new property in the common/Application class, maybe named refs.

and then we could use that (app.refs.fontawesome) every time we need to link to fontawesome search.

Also please use https://fontawesome.com/v6/icons?o=r&m=free

@SychO9, I have added a new property in the common Application, following your suggestion, to reuse app.refs.fontawesome. Please let me know if any changes are needed
