I love “paste relative channel reference” the only catch is when i
already have an expression half written it clears out what i had in
there. to work around this i use this work flow

1. copy parameter
2. on the node i have my half written expression i “paste relative
channel reference” in a parameter beside the one i am editing.
3. copy the ch() expression
4. set the value back to what it was in the parameter beside the one i
am editing
5. click else where to enter that value
6. right click on the parameter beside choose delete channel
7. paste in my ch() expression into the spot in the expression where i need it.

What if you could just

1. copy parameter
2. in my half written expression i right click and choose “relative
channel reference in buffer”
3. then i hit ctrl v and paste that ch() expression where i need it in
my expression.

As far as the interface goes it could be under the “paste relative
channel reference” or be a button to the right of it at the end of
the line. Ether way as i am making video tutorials it is a bit
embarrassing to watch myself do this drawn out step. Maybe i should
just write the ch() expression by hand each time, but why should i
behave like a computer when there is one in front of me.

Its not too hard to implement!
So Who thinks this is a good idea?
