I want to search than for users so the user i choose get an email that he got marked in a comment
or is there any plan for this. would be swet
That isn't as built in feature but it would be fairly easy to implement using the existing APIs. Listen for ANNOTATION_ADDED and ANNOTATION_UPDATED and then use a regex to look for the @ mention in the annotation bodyValue.
You could even listen for ANNOTATION_DELETED and send a follow up email to tell them to disregard the first one.
