I would append a unique worded header comment in each file you have modified. Then you can search for that unique header when you want to find all your modified files. Remember the vbulletin tool only works for vbulletin files, not files that you have additionally added to vB.

Another thing you can do is add an additional file to the server for each modified file. Call it something like: "forum.php___#fp#.php. Something that sticks out. Now you can search for file names with #fp# in them and they will also stand out in a file-manager.

There are a lot of solutions, but as long as you have a system in place you will be okay.

Sometimes there is just not a hook where you want it, but you can add your own hooks -- of course you still have to replace the hook on an upgrade.
