Definable button next to 'Archive' and 'Spam'

[Richard1]

I would like a button that would allow me to easily move emails in my inbox to a specified folder. My example is the 'Newsletter' folder.
This button should be located next to the 'Archive' and 'Spam' buttons so that incoming emails can be sorted very quickly.
It would be enough if one or two additional buttons could be defined here.
Thank you for your interest in my ideas.
