I'm new to the GDTF builder. I would like to experiment with creating and/or modifying existing fixtures and download my work in progress to test on my console. It appears that there's no way to do this -- you seem to be required to upload any changes made to GDTF-Share before you can download the resulting .gdtf file. Or am I missing something? I would prefer to be able to use the editor, download a draft version of the GDTF, test it, and make additional changes before uploading/sharing the final version. Is there any way to do this?
