We would love to be able to post alerts to Google Chat using the incoming webhooks (cf. https://developers.google.com/hangouts/chat/how-tos/webhooks ). A similar integration to the one already existing for Slack would be wonderful!

Allow maintenance window for planned IT job (server down)

Ath the moment SMTP ports may be checked for responsiveness but not for valid connections. Interesting would be: check if there is really a SMTP server check for STARTTLS check for valid certificate / expiring certificate check for MTA-STS/DANE

Ability to create group of checks or tag them to ease search and filtering.

For me, the weekly report is mainly noise when the tests are "all green". It would be nice to have an option to not send the report in this case, or alternatively to have some header or tag in the mail that would make it easy to filter it out & mark as read using mail rules.

Teams aka multiple users per account

I think a custom logo has been suggested before in a comment ( https://updown.canny.io/general/p/custom-css-for-public-status-pagess ), just wanted to raise it a suggestion now

It would be nice to have either page specific or account wide custom stylesheet applied to the public status pages. Specifically, I'd use it to draw more attention to the translation dropdown and to eliminate some whitespace.

it would be nice to duplicate a check with a button

Hi, it would be really, really useful to have a field for comments, to describe what's being monitored/why and perhaps a pointer to a documentation or something, so that the receiver knows better what to do etc.
