A great extension that fixes the annoying bottlenecking caused by a terribly designed web application system.

Great Extention. I was frustrated because of the lag. This can become a proper tool with many function that will go for ChatGPT

Hi Sebastian, the extension is great, thanks for that! GPT now is as fast as the mobile version. One question, if I need to read any message which removed from DOM (let's say a message from the last week), how can I do that? Do I need to turn the extension off and reload the page to have access to the hitsory? P.S. Sources would be apreciated ;)

Works great. I just wish the code was open source so we can have a bit more confidence in privacy.

When it works, this extension is great! The proble I've noticed is that the thread appears again (more than N messages) when I refresh the page. It makes sense for the entire thread to return, but it would be nice if, in the same way that the thread is reloaded, the extension is executed again to eliminate it immediately.

Been looking for a solution to this issue for weeks/months. Seen this on reddit hours after it was released. Installed it 5 minutes ago, already saved me 4 minutes of waiting to see ChatGPT's response. Hopefully no more blank screen or "waiting" for browser to respond. Thanks! EDIT: Still running into the same issue as before, but less. Still recommend this extension

Absolutely brilliant extension. It was so incredibly frustrating having my browser lag like crazy and it led me spiralling down all sorts of rabbit holes trying to figure it out. This extension solved the issue entirely. Interestingly, I have found the custom GPT's and Projects that I make with my own instructions slow down especially quickly (around the 20 message point) compared to normal chats that can last for much longer. You would think for a company with as many resources as OpenAI has, they could figure this out! Thank you for this extension and please keep developing it!

ChatGPT has been really lagging on my browser and so far this is working like a charm! Thank you!
