Usage and permissions

You may include any of my mods or tweaks in your own mods / modpacks, provided that you credit me and link back to this repository. Although asking permission or letting me know is not required - I would love to know if you decide to use any of my work, so hit me up on Discord's GAMMA server.

This permission covers my original work only. Third-party code and assets keep their original authors' permissions and requirements.

Special thanks to kingofthebeats from the GAMMA Discord server for suggesting lingering highlights.

It's Time To Stop (ITTS)

Tracks real-world playtime and helps you keep sessions from running longer than intended.

• Adds total playtime and current-session rows to the PDA ranking tab.
• Adds an optional real-life HUD clock with configurable placement, fonts, and colors.
• Sends configurable session-threshold reminders, with optional repeats and a PDA beep.

Inspect Weapon Hotkey

Adds a configurable hotkey that plays the current weapon's existing inspect animation on demand.

• Uses each weapon's own bore animation and sound, including grenade-launcher variants.
• Only starts while the weapon is idle, avoiding reload, firing, and weapon-swap interruptions.
• Provides MCM settings for enable state, key, modifier, and single-press or double-tap activation.
• Includes English and Russian localization and falls back to J when MCM is unavailable.
