As nobody is currently maintaining POLUtils, and nobody else has stepped up, I'll do what I can to keep it functional until someone more competent decides they want it working again. I can't update the Google repository, but Aureus has created a repository on the Windower GitHub to host the source and installers.
While I have a basic understanding of how to fix and adjust this, it's nowhere near comprehensive, so if something major changes, it's possible that I won't be able to fix this.
If you want me to add something to the file menu, that is fairly simple to do provided you have the file path already. If it's similar to other things that are already there, chances are I won't need this because of how FTABLE and VTABLE work, but it'll help regardless. Maps, mob lists etc. are generally sequential. Post the path/what it's for here and I'll add it. If you want something else changed, say so and I'll see if I have the ability to do that. No guarantees.
