@edjalmo , precisely the file that that commit modifies is a playlist like I was saying.  Anything in Kodi with an .xsp extension is an xml playlist.

So, recently watched tv show is already a playlist? Because deleting the <rule> this affect this shelf.
Explaining more my thought: you already put options to user changes in shelfs like sort by and order, so what I thought is that watched itens could be an option like that, but it seems it is not. Sorry to insist too much in this, just wanna understand if this is not possible.  

@edjalmo , unfortunately it is not, since I cannot change the playlist on the fly from a skin.  Sort by, sort order and limit can be changed on the fly, as these are parameters to be used in showing lists of content.  The rules are integral part of the playlist themselves. Addons, like skin helper widgets, have settings like that, where you can specify to include watched items or not, but using those (which you can, I have those under Additional Shelves) usually means less performance.  In my case, I will just provide a different playlist and for you it will just be choosing that shelf instead of the other one. 

Of course, this means that if at some point you don't want to include watched items, you will have to choose a different shelf.  In my opinion this is a small price to pay.

Understand! Thanks for clarify this to me.
Yeah, I already test additional shelves an is less performance (and I use a Raspberry Pi).
I think I agree with this playlist. In first time you wrote I thought that playlist was different of a shelf, but it's shows equal.
If is not ask to much, could you add too shelfs to recently added, recently played and in progress, for all types of media (music, tv show, movies, albuns, artist...)? If the anwser is yes, you need to disabler watched itens in this default shelfs, and add this new shelfs (playlists) with a label that indicate that to users, and when we add this shelfs to home we can delete the words that indicate this shelf has watched itens.
