This is a still very basic TextEdit widget for LC 8 (8.1.5 and later).
From several reasons I don't publish a LC 9 version of the widget.
[The widget is the 'widget version' of stack "HHTextEdit-Basic".]
It uses libbrowser and essential handlers of the browser widget source.
It has NO dependencies (i.e. no extern JS libs to download, uses vanilla
JS and CSS3 via libbrowser).
Download the zip-file from here, unzip it and locate it from the
LC Menubar > Tools > Extensions Manager using the plus at top right:
