Hello!
I just installed the nightly build version (Linux amd64).
It is the first time, I used this great programm.
I think there are some files missing in the eyes-folder (/data/eyes):
The "notfound.png" file and the preview files (green.png, brown.png)
Enclosed a zip-archive with the missing files and 2 new eye-sets (blue, green2).
Greetings
Juergen
