That said... I jumped to a few random moments in your video and had an "oh my god" reaction because you really were not kidding when you said that you were pasting code.
I'm pretty much begging you to install and use Cursor. Whatever boost you're getting from your current workflow, you will see triple through use of their Agent/Plan/Debug modes, especially when using Opus 4.5. I promise you: it's a before electricity vs after electricity scenario. I'm actually excited for you.
A lot of folks will tell you to use Claude Code. I personally find that it doesn't make sense for the sorts of projects I work on; I would 100% start with Cursor either way.
Would you be willing to go into more detail about that claim?
The framing of your question as though I might possibly be hallucinating my own situation might be correlated to your lack of reply.
I didn't reply because I haven't had available energy to properly analyze your reply. At a glance, your reply does seem completely reasonable, which is why I upvoted it.
