Quickly and easily add Font Awesome icons to your custom post types.
For now, yes. The next version will come with a GUI.
Not at all! If you want more functionality, check out SuperCPT, which helps you create custom post types, custom taxonomies, and add meta boxes.
Sure thing! The plugin pretty much just adds CSS to the admin which get added to the document head. Move those to your theme/plugin (not your main style.css since this is the admin panel, you'll need an admin-only CSS file). You can leave the paths the same if you don't plan on uninstalling the plugin (you can still deactivate the plugin). If you want to uninstall it, you'll have to copy the fonts to your theme/plugin and change the paths in the CSS.
add_filter( 'pti_plugin_show_admin_menu', '__return_false' ); in your theme/plugin.
