No JavaScript
The new interface you're forcing on people is a nightmare for old computers. The Basic version (basic basic, with the /b/ in the URL) worked super because it didn't need JS to be functional, I could open all my emails in separate tabs easily, it loaded very fast, and I didn't have to fish around to find the right setting.
I can still force the basic version but the moment I try to get somewhere it goes back to the /n/ version, and I can't get where I want. I know there's no way you're going to go back (because who cares about users) but if you could develop a "lite" version (without the nightmare that is JS) it would help a lot of users.
