About this extension
💡 Hit me up for possible suggestions and improvements! (github.com/nhantrichuyenanh/YouTube-Comment-Formatter/issues)

📝 Akin to a word processor, highlight a text or put the cursor in the middle of it to format it. By the same token, format it again to remove the formatting. Add-on also takes into account how YouTube formats text with special symbols next to it to avoid rendering the text unformatted and making sure its hotkeys don't interfere with browser's.

🎯 Inspired by timqueen.com/tubebuddy-comment-formatting
🔗 Partially forked from github.com/Germaphobe/yt-comments-extension
⚙️ Source code is github.com/nhantrichuyenanh/YouTube-Comment-Formatter-Hotkeys
Developer comments
NOTE:
• Community Post and Live Chat don't support text formatting while Shorts don't support YouTube's custom emojis.
• Timestamps in preview don't do anything if clicked since it would either refresh the whole page or opens a new tab, all of which are unpleasant. Sincerely sorry!
• Links are inherently quite messy so they might or not rendered properly in preview.
• Timestamps and links can't be formatted with formatting symbols, despite what preview displays.
• Unsafe assignment to innerHTML due to having to insert images into preview (YouTube renders emojis and its custom ones as images, consult here: https://youtu.be/3N8N_UIDlOc).

Release notes for 1.0.6
Added formatting for timestamps! Doesn't actually do anything, though, else it will completely refresh the page instead of actually at the timestamp.
