Previous versions of FormatList will not work with Movable Type 3.3 (or later). The new version (1.2) will only work with MT 3.3 or later.
FormatList no longer requires the BigPAPI plugin.
If you want to use FormatList with MT 3.2, please download:
FormatList adds list buttons to the toolbar, in the MT admin entry screens. For more information, click here.
Note: with this version, I have not updated the button images to reflect the new sizes that are used by MT 3.3, so you may notice a slight difference in size, compared to the new 3.3 toolbar buttons.
