Often I find I save a blueprint and then realize I've missed some small feature or change that then requires a whole new blueprint to be saved. I have to retype the whole name of the blueprint again with an increment and the catalog list gets filled up with blueprints that are only fractionally different from each other with ridiculous version numbers going up n' up... As my catalog has grown this is becoming a right royal PITA, one of those things that niggles away at the overall enjoyment factor. We need a way to be able to easily overwrite a blueprint. "Save As" or "Save New" are pretty standard features and would help reduce the catalog clutter significantly. Is there any reason this has not already been implemented?
