Please add the option to display subfolders in a collapsable tree structure like on the desktop:
inbox subfolder1 subfolder2 ...
instead of displaying all folder paths in a list like it is currently done:
inboxinbox/subfolder1inbox/subfolder...
I like the idea! The only workaround I could find after a quick search was the addon "WASD Scroller": https://addons.mozilla.org/en-US/firefox/addon/wasd-scroller/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search. But I believe it...
