WYSIWYG editor

You can use TinyMCE as WYSIWYG editor. However, the editor packages are not shipped with phpSQLiteCMS. In order to use it you need to download it separately:

Download the editor package
Copy the folder tiny_mce into /cms/modules (so the path to tiny_mce.js is /path/to/phpsqlitecms/cms/modules/tiny_mce/tiny_mce.js)
Enable it in Administration → Settings
You can edit js/tiny_mce_init.js to customize TinyMCE
