I've been using BIAB for about two decades and something that has always bugged me was the clutter in the style picker. I use it almost exclusively for Jazz and related styles, which means that there are hundreds of styles that I'll never use, that nonetheless clutter the style picker and take up space on my hard drive.

Is there any straightforward way to remove styles from the installation (i.e., both from disk and from the style browser)? Some means of bulk removal (e.g., of an entire genre) would be especially useful.
