Looking forward for the new UI in the coming update of Plasticity. I don't have studio version, so no beta for me. New UI looks promising and interesting. In the current UI I hate these black borders on the left and right. I can turn them off with ctrl-B, but then I'll loose the outliner and some options. So I found a .css file (stylesheet) and replaced the default borders with transparent ones and moved the toolbar to the bottom. Looks much cleaner to my eyes and more space available for modelling.
