At Jin's request, I'm posting this as a feature request:
I've been wondering for a while if there is any way currently to have MediaTomb somehow flag which files you've already seen.
For instance, I've been watching some pretty long series (over 150 eps) lately, and the eps names are like "episode150.avi" or such, so it's impossible for me to remember which was the last one I watched. It would be great if MediaTomb would somehow "mark" episodes as they are watched, so that the next time I will know from which episode to continue.
The mark could be as simple as a specific charater/prefix or suffix added to the filename.
