Long time WP Super Cache user here. I've recently started using Multisite in a big way. And I'm getting really frustrated with WP Super Cache not allowing me to disable it on a per-site basis. It intereferes with some of the WooCommerce widgets, and the only option so far is to turn it off. Apperantly W3TC honors WooCommerce's instructions not to cache those sidebars. But even if I started using it, I'm interested to know if there's a way to disable it per-site if there are issues?
Also, does it have an easy "Delete Cache" button in the admin bar for when you're working on a site?
