What if your tweaks don't get updated for the beta version? Reading through various ongoing threads here it looks like a lot of stuff doesn't work correctly on the beta. In the past, devs don't normally update tweaks for specific betas. Who knows, in the end it might not even be an issue. Just some food for thought.

So far though, the tweaks I enjoy the most are accessible with the beta. The few that are not I suspect will be updated, but you're right: they simply may not be- yet that is something I would live with to keep 7.1
