I feel the same way - just bought in December. What I really wanted for Christmas was Scuffham 3.0 with just a couple more amps, some pedals, and an updated UI. Call me done at that point.
Hopefully the "redesigned" UI addresses some of the sluggishness. Not sure I'm ready to dive into this but it looks interesting. Got a good deal on the Pro package around the holidays so just maybe...
