Send Info Note
Suggestion -- send a note to all email addresses, referring to the Settings icon (when you click on the Menu stripes at Top Left). This may help to address many of the concerns raised, thus prevent them getting raised as complaints, thus having your rollout look (and be) better received. And also include a link for listing (& description) of some if the new "hidden" features (such as, "long click on a message to then see the option for checkbox, to then move or delete"). Thanks for considering it.
