Where is Composers located?

Hi all

I've just found Cursor after watching another video and it popped up after. I found it interesting so I carried on watching and then downloaded it. The video I watched was: https://www.youtube.com/watch?v=oe3Jn6FRoII

At 3:43 he hits cmd + shift + i to start composer and it shows it on the left. I'm on Cursor version 0.43.6 and the composer is on the right but I used cmd + I (not shift, I'm not sure if this is different?). I'm ok with what I got but It seems a bit bunched up and I can't see how to create or delete the composer. If I add some docs and click return to go to the next line to keep adding information, it submits the request. I've had to write my text in notes and then copy it in.

I did this, created the project as per the video and my code cam with errors even though I copied it 100%. I'm sure I saw you can change what ai it uses, maybe the default one isn't very good?

Can anyone guide me how to get better results and make sure it's performing as per the video?

I love the concept so hopefully it works for me as it did in the video.

Thanks
