The My Simple Sections plugin is using a dated, but still usable core, thanks to Custom Meta Boxes by HumanMade. While this still works, I am overhauling the plugin to remove this from the core and instead create tailored code for creating custom fields, for data entry. This should remove a bit of items from the core, and allow for more items to be added easier in the future. The total size of the plugin should also shrink a bit. More information about this change coming soon!
