Thanks for the feedback. We will absolutely look into creating an updated version with fonts sorted into folders - plus we were thinking of adding some kind of preview tool into the pack to make previewing your text in each font easier.
You can also view the vast majority of fonts on our dafont profile: Chequered Ink | dafont.com
It doesn't let you sort by both artist & theme either, but it does seem to load faster and can be set to show 200 fonts per page for easier scrolling.
