button.
This also extends to SMAPI, it is capable of automatically installing and uninstalling it.
You can also install mods that are zip files by dragging them onto the mods page!
You can enable and disable mods at will by double clicking on them in the list or right clicking them.
Mods can also be deleted from the right click context menu.
