I would love to have some sort of display in a remote that would allow me to see the value of a variable. This could be configured to show items, coordinates, or just one axis of a coordinate.
This would allow for much more complex interfaces to be created for more complicated actions.
Mock-up image:

This is already possible, by putting ${varname} in your label text. ${#varname} is also accepted; both versions always get a global variable named varname.

You can also extract just the X/Y/Z components with ${varname.x} etc.

This is documented in the Patchouli/IGW guides, but I'll consider some way of adding this as a tip in the Remote editor GUI somehow.
