Hey there, you should change the greetings message, it's currently like:
"Hello <Character Name>!"
i'm sure you don't mean anything bad and it's an oversight, but it's obv dangerous for people posting logs and against the forum rules, also you should make sure it doesn't record anything else that could compromise anyone that post a log, like pet names, other toon names or target names (no idea if it does this, just saying in case).
the only thing what it does for me , is :
[SinD] Casting: Slice and Dice
[SinD] Casting: Sinister Strike
[SinD] Casting: Shiv
[SinD] Casting: Sinister Strike
[SinD] Casting: Eviscerate
what's the keybind for Killing Spree toggle
Have you tried it on a fresh installation?
If yes I am not sure I can help somehow but you can still post your latest log.
It's "Ctrl + Q".
It should show at startup
