Shouldn't CONSTANT definitions be in the Jumps list tab, for a file? It makes it slightly more awkward to locate their definition otherwise.
hm. You can put a sub __CONSTANTS__ before them. That's what I do. Not nice, though. If you have every constant in the list, it might overflow for large projects.
What's the limit on the tree before an overflow?
screen height. I mean visual overflow.
How about putting constants in their own branch, collapsed by default?
Or add CONSTANTS to the 'Go to definition' context menu option.
While you're at it, how about adding TYPES to this list also?
This would make locating CONSTANTS and TYPES so much easier.
Right now I hi-light the CONSTANT (or TYPE name) and do a search all files command (<CTRL>+<SHIFT>+<F>) and locate the definition by hand.
