I love ripping software apart, if able to, and this is a great modular collection to do so.
Even just editing certain files, closing and reopening the software and seeing where new edits end up, one at a time, was very intuitive before I found the forum topics listing how to do so.
It helped me make my own inputted High Elf Warrior Mage with just the basic free package after install.
Highly recommended to tip for this, which reminds me to do so, too!
