I can attest that the game has a bit of spaghetti-code syndrome. Many things are written in such way of thing by thing basis, making it hard to mod in a neat way. The things I modify at my mod is to take things that are already coded in the game and change values, but since the game is written in chunks, it is not easy to properly find for example the relation points of each character, so I change how much the gifts increase them. This however might bring bugs to the table, like jumping over certain events, which blocks specific scenes and even might softlock sidequests.
Hope to see the game has a code rework on future builds, because I doubt I'll be giving so much time to replicate my mod for future versions if everything is still so scattered.
For reference, "ItemInventoryDW" of the "Assembly-CSharp.dll" file has the cheat keybindings used at the DW. Hope that helps, and feel free to check out my mod file to find out where are some things. Honestly, I should have written down what I've touched and where it is coded, because after a month, I don't remember where is what.

And remember to not be rude. Everything takes time, a lot of work, and sometimes hours poured in does not even change anything. Appreciate what others have done even if they don't do what you want. We are all here to have fun, not to be manled by others.
If you have that much steam to be mad at there is no mod, do what I did. Got playing, interested if there were an easier way to advance, try CheatEngine, fail due to game being too big and lacking RAM, tried to hack with dnSpy, spent don't know how many days doing whatever I wanted and found until got bored, then uploaded it to bring others joy.
