[Digikam-users] tool to view 4 images at once on screen (personal not related to dk)

[sleepless]

To speed up time consuming workflow I am searching for a tool that can 
few 4 images at the same time on screen. For example on a 900x 1600 
screen 4 images at 400x600.
This is to quick compare automaticly generated optimization variations. 
View 4 -> select one -> view next 4 and so on and so further.

Any ideas?

Rinus
