In xfe's files and folders panel, the sizes are shown in bytes, kB, MB, etc.
Changing of "bytes" to " B" makes listing more easy to follow, and uses less space
(although you could say "a bit more boring",
or... "too efficient that it becomes inhuman").
I don't know which is more important.
Note that there is a blank space before B, in " B".
How it could look...

Forget it, I changed my mind.
"bytes" is better, and it is, just, plus one character in the list.
