Just created a better kill popup mod which is completely open source and available for everyone to use.
This mod does lean towards a more arcade-like feel but for you guys running skirmish/core servers with the default “enemy killed” pop up, this might come in handy
Upon killing a player it shows
-Name
-Distance
-Multiplier (for multiple kills)
You can find it in the workshop under “Naughty Boys Kill Popup”
Or here: https://reforger.armaplatform.com/workshop/664ED89A6DE0565E-NaughtyBoysKillPopup
(There is also a link to the GitHub page where the full mod is there available to download and edit to post as your own)
