Hi Raphael!
Sorry for my bad English. I'm trying to improve.
When a document has many variables, and they are reused in many sections of the document, it becomes very difficult to find or change something. So this is the idea of variable finder (or function call finder) like any IDE.

On the other hand, referring to the subject of the position of objects, it is natural when it has fixed location, not variable. When the location is determined by a variable should NOT switch to a fixed position. In this case, I go object by object by changing the fixed position by a variable.
