Note 10.1 WiFi newbie question

Hi

I'm new here and i dont know how to phase this for a search term.

I have a Note 10.1 GT-N8010 and I just got a Note 3. Previously I had a Note 2 which I could sync my S-Note with and everything was great (apart from the galery, more on that later). now with my Note 3 it has a different version of S-Note and they cant sync back and forth. the Note 3 can take the Note 10.1 notes but it chances them so the 10.1 can read them again.

My Gallery also doesnt work at all anymore, it is really slow and only loads the camera album, no other albums work and even the settings don't load anymore.

What i'm wanting to know is.. is there a custom rom that has the Note 10.1 2014 S-Note app and Gallery app that doesnt deminish the S-Pen abilities. The new S-pen stuff in the Note 3 would be nice but is not required.

I'm currently not rooted as I didnt have a need for it but if needs must.

Thanks in advance
