When exporting multiple abc tunes to individual pdf files, the filename gets pre-filled. However, you have to press the Enter key to accept the filename for every file exported. I have an abc file with over a thousand tunes in it and I want to automatically approve all of the filenames so I don't have to press Enter over a thousand times. The process also automatically loads the pdf into my default pdf viewer. I don't want that to happen either. Any way to make this export transparent and silent...
