0.50 Linux：NO “Show filename in thumbnail mode"?

[rmtk]

Why the "show filename in thumbnail mode" in settings/browser/thumbnail/appearance removed from 0.50 ? I do miss the function !
Is it a bug or not ? Now I am struggling in locating a file...

You have it now in the 'view as'

Thank you. I should read the changlog first, but is is a little too long.
