The sender display changes in Thunderbird's inbox and I'm shocked, so I return it to the original display.

Hello.
I'm Mandai, in charge of Wild on the development team.

When you enable ThunderBird's automatic updates, there are times when you suddenly notice a change in the screen configuration and get shocked.
When it was automatically updated to version 45, the sender column was used as the communication partner, and the direction of the arrow was used to recognize whether it was sending or receiving, huh? I thought so.
It's a great new feature, but I get confused when the sender doesn't show up, so I want to do something about it!

Let's do something!

It's easy to do

It was easy to do; just by right-clicking on the header that listed the subject, recipient, and date and time of transmission, you could select which one to display.

If it's an inbox, you can restore it as before by doing something like the image below.

It's a simple setup, but it took me a while to check the options and other things that I didn't understand.

I looked at the release notes for the first time in a while and thought
As an email software, ThunderBird is so advanced that I don't think there are any additional features to add.PlainlyIt seems like they are slowly adding features.

Thunderbird 45.0 Release Notes

It may not make any sense to you from the outside, but I decided to continue using ThunderBird for the rest of my life.

That's it.
