I uploaded custom icons to the icons folder. I did not make any changes to the folder 32x32 - when are those 32x32 icons used?
The supplied icons are 16x16. I made a different size 66x20 which also seems to work. But does not quite fill the entire calendar box. What width icon would completely fill the week/month box horizontally? Anything else we should know about making icons of a different size than 16x16?
