what you actually get

it installs mods and stays out of your way.

zip, rar, mmpackage
all three work the same. drag it in, it extracts, finds the paks, copies them over. even if they're nested in some weird subfolder.
conflict warnings
two mods trying to use the same pak slot? it'll tell you before anything gets overwritten.
profiles
save different mod combos as profiles. swap between them with one click.
instant updates
new version goes out the second it's uploaded. users get a popup on launch, click install, app restarts. that's it.
steam / epic / ms store
each platform gets its own pak folder. the list filters to whatever you're on.
5 languages
english, русский, deutsch, español, 中文. the whole ui switches, not just half the labels.
details.txt
put Author:name and Category:tag in a text file inside your package. the app shows it next to the mod name.
green = installed
installed mods get a green dot. glance at the list, know what's on.
