Looks like X-Note does that. Not sure. Omega? CM?
Samsung features and its bloatware, can only be found at Touchwiz based ROM, as this ROM is from Samsung itself.
CM & AOSP or AOKP is not TW-ROM, therefore, if you need those samsung features & bloatwares, you will not see them on these 3 types of ROM by default.
Just go into development forum of Note 3 of your device, and find any rom which TW base, you should be fine.
