elefont started following Fonts folder that automatically synchronizes fonts.
It would help type designers a lot to have a folder that not only automatically activates the containing fonts, but also replaces the typefaces in the documents when replacing the font file in that specific folder. Like Adobe has it. The process of testing fonts in publisher is very frustrating at the moment. There seems to also be a strange font cache behavior that just doesn't update fonts unless restarting the software.
