Since the ui visually weighs the addition of new projects within various "+" menu's "Project or folder" modal, I suggest adding the ability to create from a blueprint from there in addition to the more subtlety found "Create From Blueprint" when right-clicking a blueprint. See attached image.
Additionally, it might help organization to allow the option to organize blueprints under each "Space". Distance infers relationship, and currently "Blueprints" is separate below all spaces even though they may contain a blueprint that "belongs" to a particular space (e.g., "Small Website" blueprint in a "Website Projects" space.).
