How do you organize your steam library?

Arma - Games from the Arma series, except for Arma Tactics and Arma: Gold Edition which were won here.
Garry's Mod Source Games - Games which are installed just because of the resources for Garry's Mod
Serious Sam - All Serious Sam games
Sid Meier's - Sadly only 3 games currently in this category
SteamGifts - Games which were won here
Uninstalled - Games which I don't have installed or I don't play
Games - Everything else

I want to re-organize my categories but I don't know how. :/

Not played

Multiplayer

Completed

Favourites

I spent quite a lot of time figuring out what works for me, hope I can give you some tips

! BACKLOG --> No Explanation needed
! F2P - MULTI - MMO --> Games that don't count towards your inventory, or best played multiplayer
A - Great --> Most enjoyed games
B - Good --> Okay
C - Bad --> Trash
Indie --> Those games that are too original
No Interest --> They're good, just not for me like simulators
Old Classics --> Too old graphics, mechanics but in their time they were really great!

I really suck at commenting here, would be better if we could write HTML lol.

1) Games without badgers

2) Shelter

Lol, you used my categories! Recently i added GREAT and TERRIBLE though.

I name my categories with genres and subs genres. for example:
Puzzle
Strategy /real time
Strategy /turn based
Strategy /hybrid

A have 140+ games yet I do not organize :) A genius sees through the chaos :D

I dont

I just sort them by genre, but I give them cheeky names that try too hard to be clever but aren't.

pic related, you can probably guess what the categories are

i like it this way simple and practic

I started with some tool that did it automatically to begin, but then I didn't like it so much and did it myself.

Faves, Action, Adventure, Audio, Casual, Early Access, First Person, GTA, Indie, Lego, Racing, RPG, Simulation, Sports, Strategy, Uncategorized.

i don't. I use only the "installed" tab

Please, I play 1 game from over 200.

I used to have a system that went something like In Progress, Anytime, Installed (or something), Unfinished, Finished, Dislike, Problems. But I made a mistake while using Depressurizer that caused me to lose all my categories. :( So now I just use the Depressurizer settings, which can apply multiple categories based on Steam's categorization. It's not necessarily ideal for me, but I have too many games to manually re-categorize everything all over again.

Like - Dislike - Haven't tried - Meh

I used to have categories.I had 'backlog' for games that I wanted to play start to finish.'done' for games that I finished.and 'multi' for multiplayer games.That was back when I had 300 games.With 800 it's too exhausting.

got to many games to catogorize it.

1. Fav

2. BETA

3. FPS

4. GIFTS

5. Finished

6. Games

1. Currently playing
2. Finished
3. Infinite
4. Online/Multiplayer
5. "WTF this doing in my library"

1. Installed
2. Uninstalled

And then I back up the library file and take screen shots, just in case, because it would be a hassle if I lost my library file, which has happened before.

i don't organize them
