Thunderbird is finally paying attention to the UI side of things. Hopefully they finally implement the standard multiline email list view which has been on the back burner for 19 years XD
I wish they would not. I don't want any UI changes on my email client. Ever. It is one of my most important tools for work, so I don't want to tolerate anything that breaks or changes my workflow.
I am super happy user of thunderbird but if they keep doing this "modernizing" thing I will have to switch to a more stable mail client (after my current version that I never plan on updating breaks that is).
It is an application that receives content from the Internet, your advice is dreadful. Email is a primary vector for exploitation.
The modern example of fuckhead UI changes. Changing settings without having to click apply and/or OK. Changing from the "cog" icon to those three idiotic bars (hamburger?).
Interfaces are often used by people who are not IT savvy. The simplest of UI changes can mess their decade(s) old patterns of usage, the elderly are the easiest example of users affected by this. It not just their individual problem, those people then reach out for help which can be at considerable personal financial expense.
I dream of a future when normal interfaces and drop-down menus return.
This era ~15 years ago must have been peak GUI design, with many applications being both beginner-friendly and powerful. And if your grandma called, you could easily steer her through menus over the phone. Nowadays, good luck describing the latest incarnation of the hamburger icon over the phone, especially when all the other monochrome line drawings look quite similar to aging eyes.
The reason I switched to thunderbird is that it displays each email on a single line, which is sooooo much more information dense, and thus efficient! There's no better way to manage a large amount of email than displaying a large amount on screen!
They said it might be fixed before the bugs 20th anniversary, so less than one year to go, but I somehow doubt it.
