I would love to see an option to add a token to the “visit topic” link when users get an email from discourse that would auto log them in when they click on the link.
Many app based email clients - like gmail - use web view to load the links you click on that don’t have cookies saved if you may have previously logged in. The result is users are blocked from responding if they don’t have their login handy and often abandon the impetus to respond.
I think this would be easily fixed if you had an option to add a token that would auto login the user so they could immediately respond if they click on the link. An added option for how long the token lasts, would be useful as well.
