When I rename a field in Alteryx - it would be valuable for Alteryx to look at all tools downstream from the select tool and say "Hey - you are using that field - do you want me to clean up the formulas etc".
A field is not just letters in a formula - a field is a logical concept / an object - so it should be relatively easy to inspect everywhere there's a dependance on this object downstream and just clean this up automatically.
This would get rid of all the painful toil of having to reconfigure tools, change formulae, change select tools etc - that can just all go away in a puff of Aidan Magic.
