It would be extremely convenient if I could clean up the css without being forced to erase all of the unused classes.
I'm using Webflow and Udesly to maintain a Wordpress theme and I often need to replace designed elements with short-codes to extend the functionality of the element. Once the element is replaced, its classes become unused and I can no-longer clean up the css without erasing them.
Since I still need to use the css, I've installed a WP plugin that stores code snippets and loads them onto the site. I'd rather not manage css in multiple places for a few reasons...
You get the idea. Being able to choose which unused css classes get removed will let me store all the styles produced in Webflow in one place, even if the element no-longer exists in Webflow.
