Juk has a 'rename file' feature that automatically renames audio files taking info from their id3 tags. For example we could rename a file as its track number and have 1.foo, 2.foo, etc. But many software order audio files alfabetically, not using id3 tags, so Juk should also put a '0' before each single-digit number (i.e. 01, 02, etc) so that they come before 10, 11... Reproducible: Always Steps to Reproduce: 1. 2. 3.
