Grammarly is great but the extension is missing a critical feature - it cannot be disabled by default for all websites and only enabled manually for some on which it is needed, let it be gmail, reddit or facebook. Switching it off for every website except some is troublesome and disabling extension until it is needed is even more so. It would be also great to have a way to enable spell checking for websites on which it does not work by default - maybe context menu item "Enable Grammarly" - for example hukd.com comments don't work with grammarly plugin. Please fix it and 5 star rating will be the well deserved rating.
