As a proof-of-concept 1.0.5 works, let's hope the next version will be more useful. Puntuado con 3 de 5 estrellas

The idea is very good, but so far "interactive themes" from thunderthemes.com are installed with restart like normal themes and not on the fly, while that's the greatest advantage of using "lightweight" themes.
Also, lack of the basic instructions, e.g. whether Personas extension is required or should be disabled. It's not obvious.

Esta valoración es de una versión anterior del complemento (1.0.5). 

You are correct, right now thunder themes provides XPIs.

This page - http://brandthunder.com/personas/getmore/ - provides themes that can be installed with one click.
