 - disable-mobileindicator: This is the patch inspired me to start working on CutTheCord. It makes your device act like a desktop client, and disables the "mobile indicator" on discord. However, this breaks notifications.
 - experiments: Enables some dev-only things, like developer options tab or a secret staff-only, half-assed AMOLED-optimized theme called "pure evil". The developer options tab does not work.
-
+- hideunusableemojis: Only shows the emojis the user can actually use (mostly hides custom emojis from other guilds when you don't have Nitro).
 - hqavatars: Uses 256x256 variants of avatars instead of 128x128.
-
 - **litecord**: Changes the server the app connects to, and specifically tries to connect to a Litecord server. [Litecord is a FOSS re-implementation of Discord's backend.](https://wildcard.elixi.re/i/l3lxhd3a.png)
-
 - **mutant**: Replaces official twemoji emojis with [mutant standard emojis](https://mutant.tech/), and injects custom mutantstd emojis to the app. Second patch I ever developed!
