I work with seniors on computers in the Tucson Az area.
The new release of Thunderbird, is a bit confusing for them. The tabs cause issues, and the displaying of folders on the left side with the different views is causing panic.
Wish there was a way to turn off or not display the arrows on the left side display
(all folders, unified folders, recent folders, favorite folders, unread folders)
All Folders is all they want to see, because many seniors click without knowing what they are clinking, will turn off the all folders view option, and panic because they think the folders have disappeared. I have had a few decide not to use Thunderbird for this reason.
