Links can be inserted at the TTMSFNCWXHTMLMemo.
However, the handling is only designed for copy/paste of URL's.
Local files can be linked, but the paths must be copied e.g. from the file explorer or entered manually. Therefore, it would be ideal if a search option was built into the dialog (see pictures, the second picture is from Joomla).
