What the heck were they thinking when they removed a most basic feature such like easy and mouse-acrobatics free folder view switching from Thunderbird? How is one supposed to cope with a more complex folder structure and multiple accounts? Seems the people at Mozilla recently try their best to work *against* a positive user experience...

Thank you for this add-on. This is a must for people that still want order and oversight in their mail client, even with more then a few mail accounts and folders.
