I’ll update my JetBrains repo or feel free to send pr if you see any adjustments needed
Sure, I'm just experimenting the settings performance impact
@ScriptedAlchemy are you still maintaining your jetbrains repo?
With the new 2024 updates I'm getting so many IDE freeze/lag issues
Send a PR if u have updates. I know the jetbrains guys so I'll ask them for advise on a 2024 update
