I was surprised to find that this category didn't exist yet.
This is no longer the case, thanks to we have an appropriate category for xWidget
Customization > Skins & Themes > System Monitoring > xWidget www.deviantart.com/customizati…
We're moving xWidgets to this category now, you might get some notes
Info: XWidget is a free desktop customization platform. It’s light, handy with powerful visual widget editor and very smooth animations.
Official website: xwidget.com/
(Oh and before anyone asks, no, I'm not abandoning Rainmeter)
Thanks, if there are any concerns about the customization sector, please let me know in the comments!
