Also a bit late to the discussion,
@veermetri05 , hmm I wonder what you mean by Multiple selection of waypoints, AFAIK it was included in the 1.4.0 release. Also there was a PR I made a while back for direct copy/pasting waypoints, and there are ways of copying/pasting waypoints even without it you can check this post.
Also, I have to agree even though it wasn’t initially made for it, but synfig could very much be used for motion graphics (I am no motion graphics expert though so don’t quote me xd but I also noticed it is quite simple to make some good small demos even for me)
Personally I think future is pretty bright for Synfig, just a matter of “time” hopefully : ).
