AVA Mod Manager is a Windows program that keeps the mods, profiles and savegames of several games in one place. Each game has a section of its own, built around the way that game really works with mods: Farming Simulator 25, 22 and 19, Euro Truck Simulator 2, American Truck Simulator, BeamNG.drive and The Sims 4.

In every game
- All your mods in one list with pictures, search, filters, sorting, favourites and a duplicates filter.
- Mods are installed from a file, from the Downloads folder or by dropping them on the window. The manager recognises which game a file is for.
- Profiles: sets of mods for different savegames or ways to play, switched in one click.
- Conflicts and health: mods that change the same things, broken files, and the game's own log sorted by the mod behind each error.
- A restore point before every change and backups on demand, so any step can be taken back.
- A dashboard for each game that names what needs attention and leads straight to the fix.
- A guided tour for every section and a tip of the day.

Farming Simulator 25, 22 and 19
- Mods as tiles or a table, with chips for vehicles, maps, placeables and scripts. Every mod has its own page: the description, everything it adds to the shop, the keys it binds, dependencies and the savegames that use it.
- Play window: pick a savegame and where to start in it, at the farm, in a vehicle or on foot anywhere on the map.
- Savegames with the map, money, play time and the mods they need. Missing mods are switched on or found right from the list, and you see whether a savegame really uses each mod it names.
- Career editor for money, loans, rules, time, weather, farmland, prices and contracts. Vehicle editor: sell, repair, wash, fill up. An interactive map of the farm.
- Mods for friends: share a savegame's mods with a session key. A friend types the key in and the manager downloads and installs everything.
- Shop: everything your mods add to the store, with sorting by price, power, capacity and working width, and a side by side comparison.
- A catalogue of maps and vehicles with 3D models.
- Twelve tools for mod makers, from a check before release to a store icon made from the 3D model.

Euro Truck Simulator 2 and American Truck Simulator
- Mods in .scs, .zip and folders, and your Steam Workshop subscriptions, each with the game version it was made for and the DLC it needs.
- Mods are switched on in the game profile you pick, the way the game does it.
- Load order shown as the game reads it. Smart load order explains every step and shows a preview. Map combos tell you what is missing.
- A check before Play, and a reading of the game's log after the drive.
- Game profiles and save slots, a savegame editor for money, experience, skills, parts and paint, a logbook, your company on the map and the cargo market.
- Multiplayer: TruckersMP servers and events, whether your game version fits, a guide for rolling the game back, mod lists for a convoy.
- Every map, city, company, truck and trailer in a catalogue, with trucks and trailers in 3D.
- Radio stations, graphics presets, control sets, a photo album, and tools for mod makers.

BeamNG.drive
- Drive window: pick a map, a spawn point, a car, the time of day, weather, traffic and gravity, press Play, and the game boots straight into it.
- Build window: assemble a car part by part, tune it and save it as your own configuration.
- Cars with their numbers and configurations, a comparison of two cars, scenarios started from the manager.
- Profiles as cards, with recent changes and Undo.
- Multiplayer for BeamMP: the server list with maps, players and mods, the mods BeamMP downloaded and how to clear them, your own mods switched back on after a session.
- After a game update: which mods are older than it, a start in safe mode and a cache clean.
- Console commands with descriptions, the game's hotkeys, packing and unpacking mods.

The Sims 4
- Mods and custom content kept apart by what each package really holds, with thumbnails read from the packages.
- Collections: saved sets of switched on mods.
- Health: script mods built for the wrong version, conflicts, broken and duplicate packages, files nested deeper than the game reads, crashes traced to the script mod behind them, and a search for the mod that breaks the game.
- Saves and the Tray, with a note on households that wear content you no longer have.
- A warning when a game update switches your mods off, with a button to switch them back on.
- Play without mods, clear the game's caches, cheat codes.
