Applying edits to Noto emoji

I have made some changes to Noto emoji by Inkscape and I wanna apply to the source font. (Inkscape is a vector editor)
Can anyone recommend some open editors of color fonts? Thanks a lot.
I am now trying BirdFont and FontForge to test whether it supports color fonts.:)

SwiftKey has TWO emoji buttons??

hey!
does anybody else have TWO emoji buttons in the bottom row? one on the left, between 123 and [space], and one on the far right, that sometimes changes to a Return arrow.

it's SUPER annoying. I keep hitting it instead of 123, and deleting stuff I accidentally wrote there is even more annoying because backspace is somewhere else than expected in the ****ing emoji tab.

driving me nuts. any ideas?

this only happens on this device. everything fine on my lg g4.

happens with Stock AND Cyanogenmod Nightly. which is awesome btw.
