I like that their customer support team responds quickly to any questions or requests for help. They are always willing to work with us on customizations beyond what's included in the standard package as long as it makes sense from both our perspective AND theirs! There isn't much about this plugin to dislike - we're currently using it primarily within one department at my organization but if another was looking into adding more features then this might be good fit. Using the Chat Heads widget allows users outside your app/organization see who else has access to your org so they don't need to have open up Whatsapp and check out each other profile information. We now get feedback when someone adds something new inside our chat room without having to go through email notifications, which saves some time since there will only be emails sent every few months anyway.
