1- marking seen episodes in TV Shows by system ( for classic theme )
as some of other smart stb platforms, when client has watched 90% of a TV SHOW's episode ( till the end before ending writing and casts ends ), he/she stops or skips to the next episode or... may be he/she doesn't desire to continue. next time ( one day late or longer ) ofcurse he/she will forget witch episode he watched or doesn't.
If the system marks the watched episode with a simple check mark behind it or highlighting it, he can easily find out the watched episodes and theres no need to check episodes one by one.
For example you can see this ability in KODI.
I hope I was succeeded to describe
2- resume support ( for classic theme ). (( Not Ended option not working correctly and its hard to use for clients ))
