- font change doesn't not effect i think it's because of removing extension from chrome web store

- FINALLY! Being Deaf, I need captions on YT videos. But their "defaults" are NOT suitable to my needs. And Chrome often "forgets/resets" MY preferences to their default. Which forces me setting up captions every friggin time. You've spared me a real bothersome chore. Well, there's no drop shadow option. Never mind. I love your extension just because it remembers my choices. Please, don't let the marketroids in Google kill this extension, just because it does a better job than the original YT captions.

- Please update to Manifest V3. I updated to Google Chrome 127 and I received the warning message "These extensions may soon no longer be supported" that was including your extension. I searched up what caused of this warning and I find out it was effected only or the Manifest V2 extension, which is I think you using Manifest V2 to make this extension. So please, update your extension before it was unusable in 2025, please!!!!😭😭

- I love this extension! Easy to use to create colorful subtitles with endless possibilities. Only issue is that I can't get the font to change on Netflix.

- I really love this extension, it added more life and color to what I was watching. I love it!!! But two suggestions too ============================================================================== ● To have custom subtitles for each website ☉ For example, I want purple themed subtitles for YouTube but a red one for Netflix. ☉ Basically just some slots for each website. ● And to see what the font looks like without trying them. ============================================================================= 10,000,000,000/10 Would recommend. Great Extension. Keep up the good work. I hope you guys get more and more popular as time goes on :)))). It's okay if you don't really respond to my comment :')))))

- BEAUTIFUL DESIGN, SO USEFUL & EASY TO USE :D ----------------------------------------------------------------------------------- thank you so much I have been looking for something exactly like this! ------------------------------------------------------------------------------ Possibly some awesome features to add: drag & drop multiple languages and multiple instances image import or selection for background or stickers for frames & layers for video this may be available in another extension so if some of these can be added through another don't stress it. Thank you for the amazing creation :D
