Face recognition: from thumbnail size face previews to huge face previews. How to change size of tiles...

[bw89029891]

Hi all-

since face recognition is available I worked on my 4K screen with a matrix of from thumbnail size face previews that was approximately 16-20 preview tiles wide. all of the sudden I see huge preview tiles where only 3 tiles fit in one line of the matrix. probably I have unconsciously cranked up the size, but all attempts to reduce the tile size failed. Can anyone help?

Thanks in advance and all the best,
