I really want to like this product and I've compared it against a few other Chrome extensions that does the same. The problem is I noticed that this slows down my Gmail. When I navigate around my gmail (opening inbox, navigating tabs, switching to new email), it takes a few more seconds than usual. I disabled my extensions and realized that this one is causing the issue. So unfortunately I can't use this product :(

I also email support and followed up but never heard back from him. And based on other reviews, it seems support is not very strong. I'm guessing it's one person doing all of this and he's overwhelmed by everything.
