Mozilla is asking for feedback about Thunderbird and threatening a redesign. Thunderbird is the most feature-rich of the GUI mail clients, but as a result also has a lot of cruft. The goal of the survey is to learn what Thunderbird users think about the current design, what are the biggest drawbacks, what potential changes should there be, and so on. The claim is that the information will be considered before any actual changes are made to the program itself.

So if you rely on Thunderbird for any part of your work flow, speak up now before it ends up unusable trash like M$ Outlook or Apple Mail.

This is is not good. I like Thunderbird and I do not want it to change. Sadly it looks like there are no real alternatives, at least not for me yet.
Today I tested quickly Claws mail, and I found it not to be a good alternative. Claws is terrible with high resolution screen. Also, the quick filter is less good as you can search only one field (for example only subject) rather than several fields. I am using a tiling window manager, and I found it frustrating how Claws do not automatically adjust the field widths in the main panel, according to how wide the window is.
