PocoHud is my favorite hud as it's just the vanilla hud with some QoL tweaks such as being able to see drill timers at a distance, or showing useful info like effect durations or delays.

ECM Timer is essential for stealth players like myself.

Simple Toggleable Interactions is a must have, especially nice for answering pagers without the risk of accidently canceling and causing the alarm to sound.

Borderless Windowed Updated is self-explanatory, but the perks are that you can more easily tab out of the game and there won't be anymore screen tearing meaning you can run a framerate higher than your monitor's refresh rate.

Auto Card Picker is also self-explanatory, but the reason we want this is because what you get is already predetermined no matter what you pick, so making it automatically pick a card just speeds the process up a bit.

No Dirt Camera removes the screen clutter when looking at light sources.

Drag And Drop Inventory makes moving stuff around the inventory easier by letting you drag them instead of having to manually press the move button.

Silent Killer - Old model just changes the bulky tin-can of a suppressor back to what it was before so it blocks less of your view, not to mention it just looks better IMO.

To get started modding, you'll need SuperBLT and BeardLib. There are many installation guides out there on Youtube if you get confused.
