the new design is simply awful!!!! I'll probably swicth to another email client if I cannot roll back. But then I do not want to get stuck with an old version of thunderbird, probably better to switch to another email client now than later anyway.
it is terrible! I don't know who the design team behind the scenes is, but they completely messed up with the new design. Is there a way to roll back to the eralier version? If not, I am afraid I'll switch to another email client.
