shows "Today" and "Clear" icons for calendar and datepicker popup
{ view:"datepicker", icons:true }
Text of the icons may be altered within the current locale as:
webix.i18n.calendar.clear = "Clear New";
webix.i18n.calendar.today = "Today New";
webix.i18n.setLocale();
Locales can take HTML as well, e.g. you can include span elements with icons.
