Selection of the folder view by 3 or 4 buttons above the tree structure

[DanKu]

Hello everyone,
I really like the different view options for the folder structure in Thunderbird. However, I find it unfortunate that the different views are simply stacked one below the other.
I would love it if I could simply choose how I want to view them using three or four buttons above the tree structure.
I could imagine:
1 button = all folders
2 button = only folders with unread messages
3 button = favorites
4 button = customizable

This way, you can easily switch between the views depending on your current interests and find what you're looking for more quickly.
I personally find the current solution somewhat ineffective.
