If some of the user friendliness has to be sacrificed to make some of these elements work, can I suggest giving Bitsy two different modes? Essentially a "basic" and "advanced" mode, having a few more tools to play around with would be great, but splitting them up in this kind of way would just mean new users wouldn't get overwhelmed by the number or complexity of the tools.
Yeah, that might become necessary eventually. For now I'm hopeful I can avoid modes by adding functionality via new tool windows - that way new users can add tools as they need them. One thing I'm considering is preset "workspaces" that open a set of related tools automatically.
