I use Thunderbird. Whenever I create a new folder in the email account I have set up in Quaker Meetings Network (QMN), url https://quaker.app, it is appears as a sub-folder of Inbox, but I want it to be a folder at the top level of the email account. I can do this with the other email accounts I administer with Thunderbird, in gmail.com and phonecoop.coop. Why can't I do this with a QMN email account? QMN say this is an issue with Thunderbird -- they are able to create "top level" folders on other email software such as Outlook
