Add settings option to always show macro knobs

More and more patches use the macro knobs, and I'm so grateful when sound designers do this. Whenever I open a Unify instance, either standalone or in the DAW, macro knobs aren't visible by default. I'd like to enable an option to always show the macro knobs. Would save a lot of time especially now that 100% of the tracks in my DAW are Unify, so opening and closing Unify on each track happens often.
