Uhg. This is the exact opposite of what direction I want from Thunderbird. I want it to remain stable. I want it to remain looking like an email client I run on my native OS. I do not want giant white-space webshit design and an entire rebuild that makes all my extensions and well trained spam detection .dat unusable.
Please stop changing things just to change. Thunderbird works.
