A one stop plugin for all your fonts, FontMeister pulls fonts from Google Web Fonts, Typekit, Fontdeck and Font Squirrel for you to use in any theme.
Support is planned for Fonts.com and other providers. If you have specific suggestions do post them.
FontMeister provides a function
add_more_fonts that can be used by the theme authors to augment their
list. Alternatively they can define their own hook and provide it to me and I can add the support natively in the plugin.
Yes, for Font Squirrel. In some cases while downloading a font from Font Squirrel the resultant zip file is empty (0KB). In most cases this happens for larger zip archives. The issue resolves itself if a download is reattempted after an interval of time. Alternatively you can manually download the zip file and unzip the contents to the "fontmeister" directory in your "uploads" folder.
