Wiethoofd@Hidi That's a convar to indicate your healing target: hud_medichealtargetmarker and appears above the player being healed, set to 0 to disable.
@eevove, which notification panel where? the one top right in backpack stuff is a file in the econ folder, positioned in the charinfopanel, the ones in the main menu should also be in the econ folder, the filenames should be clear and otherwise figuring out an element name and using your 'in file search' in your editing program could help narrow down the list of files responsible
You're a dank person, thank you very much!
