Discord Emoji Picker — bring Discord’s emoji experience to Obsidian
Demo gif:

Tired of copy-pasting the same emojis over and over? Discord Emoji Picker gives you a Discord-style picker powered by your own custom emojis and stickers — your images, your sets, your rules.
Emoji & sticker picker with sets from your vault folders, live search, and recently used
Insert as :shortcodes: (rendered right in the editor), native embeds, or HTML
Import custom emojis & stickers straight from your Discord servers (user or bot token), image URLs, your clipboard, or public emoji packs
4 themes (Default, Compact, Vibrant, Minimal); works on desktop and mobile
Runs fully locally — offline by default, no telemetry. GIFs and APNGs work; Lottie-only stickers are skipped.
Install: through the community directory (https://community.obsidian.md/plugins/discord-emoji-picker), or download the latest release from https://github.com/KuroTheCoder/DiscordEmojiPicker/releases/latest and copy main.js, manifest.json, styles.css into <Vault>/.obsidian/plugins/discord-emoji-picker/, then enable it in Settings → Community plugins.
