+- Showing build percentage as dots
+- Custom thread number, 0 to disable multithreading
 - Posts in draft state (will not be compiled)
 - Check if external tools (pug-cli, html2gmi) are installed
-- Fix and optimize differential building
 - Static code syntax highlighing
 - Override internal HTML snippets (meta lines, page lists, ...) with config file in Templates/NAME.ini
 - Specify input folder(s)
