[Feature request] Expressions editor - Presets

[pgilfernandez]

I've been playing with expressions this weekend and I have some suggestions, this is the very first one:

Filling up "Bindings", "Calculate" and "Definitions" for each parameter you want to add an expression is pretty time consuming.
I would like to suggest something like the following:

A preset row where you can:

• select previous created presets (they always save "Bindings", "Calculate" and "Definitions")
• add a new one with the data you have in the 3 fields
• delete
• edit assigned name
• additionally it would be nice to have a way to easily import and export...
