We have improved Templates plugin for CKEditor. Now it has dialog mode and titles displaying feature.
You can set its displaying mode to dialog instead of dropdown by setting option:
config.doksoft_templates_use_dialog = true;
To show titles under according templates use:
config.doksoft_templates_show_titles = true;
If you are still want to use dropdown menu (popup), the new option for its width is:
config.doksoft_templates_popup_width = 375; // By default it is 375px
Also syntax of custom templates definition changed a little (to support titles and raw html form). See more on the plugin's page.
