Add an option to have into the menu View/Thumbnails 160x120

[oops66]

Hello,
Request to Add an option to have into the menu View/Thumbnails Size (160x120 or 150x113 or maybe better a new entry for a free size of the thumbnails) : thumbWidth=160 thumbHeight=120 . Because usualy on common screen 128x96 is too small and 192x144 too large.

thumbWidth=160
thumbHeight=120
