Having the ability to sign/encrypt compounds for distribution is essential to fostering a viable ecosystem
Much better ability to preview and organize externally-sourced nodes and compounds is another obvious, critical need -- the current node panel is terribly inefficient for that, names alone aren't nor have ever been adequate labeling as to purpose/contents of substantial quantities of entities of any sort. Having some kind of visual preview of the node flow itself, along with embedded descriptive metadata (author, name, version, description, etc.) would be significantly more efficient.
