Sometimes you need to find where a prop, eVar or something is set inside a launch property. If a rule or data element is misnamed or documentation isn't up to date it can be very difficult to find.
It would be amazing to have a "code search" feature so you can search for exactly which rules lead to the setting of a variable. You could also find how data elements are set much faster in a similar manner. Other tag managers have this feature and it can be a huge time saver for new starters or consultants getting up to speed on the analytics implementation.
On top of this, when viewing data elements it would be extremely useful to be able to see every rule they are currently used in and vice-versa.
