Eg. it does '#57 A4liquid.rx2' instead of "#57 A4 liquid.rx2". I'm assuming it should be the latter? It would be very helpful if it was (if for no other reason than readability). Note number and key at the start of a file is useful sometimes but I find for me most of the time I want the info at the end eg. 'liquid #57 A4.rx2'. When the info is at the start it disrupts viewing of files as groups when they're sorted by name. I'm trying to batch rename files to swap the info to the end but not having that space there makes it difficult to do so.
Alternatively feel free to add a 'suffix' option. Same goes for BPM too. :-)
