I'm trying too to be able to switch between open chords and barre's and also to play scales all in a fluid way. I do it haltingly just now.

It seems to be a sort of mindset to switch between grooves, especially when you've been practicing one of them for a while to try and improve them. My hand seems to need to reset between and that halts the natural flow.

Like all things I'm sure it'll come with time and effort.
