Has anyone written up anything explaining the various icons in the pix folder and how and where they are used? The folder names with just letters are not very descriptive and although I can figure out from their contents usually what they are it would be nice to have a "gallery" of sorts explaining them. The mere existence of these icons within Moodle poses a bit of a challenge for me, because in an online course on hieroglyphs, things that look like hieroglyphs but aren't hieroglyphs are a bit incongruous. Therefore, I am going to need to change a lot of them so they don't look out of place, by replacing them with appropriate hieroglyphs instead. Hence, any documentation would be helpful.
