Alchemy Beta

So i downloaded and are am using the new Alchemy Beta viewer, and i love it load time is really really really fast. takes a wee bit of getting used to as buttons are in different places. and a big ol hint, when you first get it, change the location of the caches as there are reports of conflicts with other viewers causing issues. Very simple to do, just open prefs before signing in, change location of cache files, close and restart, all done forever ok folks, any one else using it and what do you think of it?
