Highlight all references to heap-allocated values

Hey, nice tool! Here's a feature request.

When you point the cursor at a reference (@147), it currently only highlights the heap-allocated value frame in red:

But it would be nice if it also highlighted all the other references to this value in yellow, like this:

For one, this would give you a clue of what the function is named.
And you would immediately see how many references there are to this function.

Actually, maybe even more generally, make it so that when you point at a reference (e.g. @147), all the identical references are highlighted, including the one you're pointing at
