This mod manager currently works for Dark Souls 3 and Sekiro with the original Modengine

Just have mod directories in DARK SOULS III/Game or Sekiro's root directory
The mod manager should then detect your mods when you pick your drive

Boot up any modding tool easily by clicking on "Pick Modding Directory"
then navigating to your modding folder.
Check the dropdown after that, then just click on whatever tool is there to launch it

KNOWN ISSUES:
When you swap a mod by clicking on one of the checkboxes, it works fine, but previously checked
mods will still visibly show up until you mouse over them
This is not a problem because I tested it, and previously clicked mods will be inactive no matter what

If you try launching an old version of MapStudio, the layout will fuck up for some reason,
so use the newest version because this issue doesn't exist in the newer versions
