Comments too short

I wanted to add a comment to the automatically generated folder name of some new transferred pictures. While I could enter somethings the length is far too short. I'm used to adding long and detailed comments but I could only add three words after the date.
Did you limit the length intentionally?
Could you change the variable so that one can add the maximum allowed characters for a file system like NTFS?
