Now I choose "Choose shortcut" or "choose widget" and I see "Smart shortcut" - but they both empty.
also in the choose shortcut button, the smart shortcut is the only item now (all the rest dissapeared)
what i'm doing wrong ?

See the readme... you have to enable the smart shortcuts by setting some skin Bools in your skin to true.
For example Skin.SetBool(SmartShortcuts.playlists) --> enables the smart shortcuts for playlists

currently I use script.skin.info.service by Phil for some thing I will glad to see in your script instead.
1. http://i.imgur.com/HdwMLaN.jpg - cdart for moviesets [Set.Movie.%d.Art(discart)]
2. AudioLanguage of movie, which return: ENG \ ITA \ RUS or something simillar according to the audio tracks
3. Artist.Albums.Count - to count the numbers of albums for artist
and more things from that addon will be great, I want to use few scripts as possible.

I will take a look if I can add that in (if phil agrees)

4. As I requested before, to create "smart background browser" that I can use from skinshortcuts, for exmaple, being able to add menu "youtube" add assign to it the Fanart from the addon as a background.

Use the smart shortcuts feature for that... I will see if I can add the YouTube addon too but I'm not sure if that even provides fanart ?

5. as I write this, I get scripts error from the script, and also from extendedinfo which says invalid ID and more stuff, ill post maybe unicode errors, or the fact i'm using mysql server... ill check it out later.

Yep, unicode errors... I did'n't really test that. Glad you did ;-) Thanks.
I fixed the ones you reported on Git.
