I have lots of widgets for different purposes, and I forget what each is for. Suggest you add a description field to every widget so we can identity what it's used for. i.e. "website booking widget for WordPress", "cleaner calendar for property X", "property reviews for Facebook"
I found a temporary workaround that I'll share if anyone is interested.
You can add a comment in the CSS section. For those non-web-geeks, CSS let's you define styles - colors, fonts, etc.
But a comment is ignored. Like this:
/* This widget is used in my rental business website. Don't edit it! */
/* This widget is to show reviews on PM website*/
/* Testing */
Yep, that's a great idea. Easy to get crosseyed when staring down a huge list of widgets.
Will add it to the dev list.
