I've just downloaded and installed the Beta Minion. Looks absolutely fantastic, and works very well. Kudo's to the Alpha testers and especially to Shirik for all the hard work and time vested.
There's only one issue I can see at the moment. I found the fields to input a user/pass under Tools>Options, but it did not allow me to login. This only affects my ability to Auto Update one addon, nUI+. In the main listings page, it recognizes that nUI is installed, but it is prompting me to update to nUI Lite v5.03.01 whereas I have nUI+ v5.03.5 installed.
I fully understand this is just the Beta release, and things are still being worked out, just wanted to let you know.
