Actually I AM that guy with a small font size and super-packed density. The more information on the screen, the faster I can take it in at a glance and find what I need. Sorry your brain doesn’t work that way, but less clicking and scrolling absolutely does affect my productivity and my idea of usability. For example, I find it highly annoying when a website changes to a larger spacing on a drop-down list and suddenly something I used to be able to immediately click on now requires me to scroll down several times to find the option I want. I’m not sure how that’s supposed to increase usability.

Heh I just ran into the invisible icons issue recently, for whatever reason I am no longer able to accept Teams meeting. Yeah that’s definitely a shitty thing. But more whitespace? In other words, less visible information on the screen which requires more scrolling or clicking to other screens? Sorry, that just sounds annoying and less productive.

What do you find “old-fashioned” about Thunderbird? Do you not consider an interface “new” if they don’t change it and hide all the common features every five minutes like Microsoft does? It’s an email client, you read your emails in it. How would you do it better?
