Great suggestion @Conehead1978 I feel that this could really useful for Google Workspace users. By adding Google Chat, Thunderbird could become useful for individuals, small business right the way up to enterprise, with a unified notification system for email, calendar and chat. Using chat in a browser and email in Thunderbird is cumbersome and inefficient.
Yes please integrate GOOGLE CHAT into Thunderbird. I know Google stopped the "Talk" Protocole and also does not support XMPP (or has anything changed?) - and i'm not sure if the API for the new Google Chat app / system is available. Yet chatting to Google Accounts is an important feature in my opinion. Please try to integrate this.
@RR_MarcoI'm not sure if Google Chat is data-leaky but my experience of Google Workspace has been that it's quite robust. They do make quite an effort to ensure that Workspace data is kept private and constantly update it to keep everyone safe.
I'd love to see this too @franick, there is actually a proposed idea here, would might want to vote on and maybe add your thoughts to. I'm not sure if Google Chat is somehow proprietary that might prevent it working with Thunderbird, but if there was a workaround, it would be really useful.
