UI space is not about size but about combinatorics.
Oh yes, the idea that unused elements can be hidden was the first when I saw a plugin :)
Daniel, i like the plugin so much that I decided to help with the development of the interface. I hope you will like it. The design is not a pixel to pixel, I only had a screenshot. And this is not necessary, because you have a vector. I did not even adjust the font one to one. Did not spend time on that you will redo anyway. Just picked up a similar one. It is a scheme. And yes, i've added three more randomizers without increasing the size of the interface or reducing the size of the elements, sorry :) The plugin is the same body and element size fully open. And much smaller in minimal variant. And the plugin needed better color coding. Now it has.
Have a look
