New UI is great, buttons will take some getting used to but it beats losing 35 hotbar spaces any day. I think my only gripe is that they should have made performance a main command rather than a separate tab so we could set performance to our hotbar and then select an instrument to play. As it is you have to take up 4 hotbar slots to set all instruments instead of just having one “performance” button and it will only take more space as more instruments are added.
