How to add a buttin in the panel

[leonardvb]

Hi guys , i don't know if this is the right threat for this question but , how can i add a icon and button in the panel , or is it even possible ? i need to link to an outside control panel for vps . So i want to create an Icon that matches the default in Sentora and then add id to the panel with the option to link to the url of the other control panel and open it in a new tab. (target defined)

Does anyone have done this before ?

Kind regards Leo
