Universal robust map markers for GZDoom
I made a simple mod that adds customizable map markers for monsters, keys, weapons, ammo, health, powerups and other items. Optionally, markers for items dropped by monsters can also be created (but changing this option will only affect items that are dropped after the change).

No need to unpack, just run it as you would run any mod.
The mod uses MIT license, so you can use it pretty much for anything.
