I think TCB waypoint is great to for more fluent and natural movement, I love to use it. But when I have multiple layers that I want to have same TBC parameters (i.e. Tension, Continuity, Bias and Temporal Tension) it’s tedious to go through layers and edit multiple waypoints in each one of them.

Is there way to like easily copy and paste those parameters? I tried exporting value on waypoint but it doesn’t export parameters

No, there’s no way, sadly.  
Feel free to drop a feature request on GitHub: [GitHub · Where software is built](https://github.com/synfig/synfig/issues)

TCB interpolation is in pretty raw state right now. There’s still no graph (curve) representation of all those TCB parameters (tension, bias). It’s very hard to get what you want without any kind of visual help.

Ahh, I figured

And that is why I use graphs tab to see what kind of changes are made when play around parameters
