Ditto the same. It feels like its catered more to small-mid sized it needs to be more condensed and treated as an Enterprise application, not your mom-dads Quick Books or Turbotax UI. It has alot of visual bugs, context menus are odd, some font is like 48px etc…
I also preferred the dark theme, especially if you look at it all day.
@hmwillett in a browser the whole open with is going to be a bit tough… it was nice to bring up mini window as popups in WinForms… Users will get lost in tabs 
or the whole drill down. In an Enterprise level atleast.
As far as functionality its still Epicor, love it.
