Seriously. I`m wasting hours of my life installing almost 300 packages from mods in the new RF2 UI. How can I select and install multiples packages at once? In the old UI, it was so easy... Also the "Refresh" button don`t work. It does nothing.
I'd suggest a quick revert back to the default UI, do your "one touch install", then opt back in to the beta UI. 1 to 2 minutes to swap UI. Just remember, at the moment, the choice of UI is yours.
