[Pharo-users] GTPlayground or STPlayground

hello everybody! What are the difference between the GTPlayground(that I think is deprecated) and the STPlayground? for my live coding performance the GTPlayground looks better because it is more “stripped” down, but does it work fine as the STPlayground. also, if I would like to chance the appearance of the STPlayground, which would be the methods to get rid of everything in the window except the window itself and the title. thanks a lot for your help. d
