Like some of you, I've done a few hacks to some WP core files (e.g. to simplify the posting page for my Authors).
The issue is that everytime there's a WP upgrade, I have to re-do the hacks.
I'm aware that it's possible to download the changed files for each upgrade. But is there an easier way to compare files directly and make the file changes without, say shell access on a server.
Just wondering how other people maintain there hacks when there's a WP upgrade, and what's the easiest & efficient way to do this
