I went the same way but found that the GUIs (Claude and Codex Desktop) are still too low-level to scale well. They are basically just tabbed chat windows. I wanted more structure and more targeted UX for managing my work. It's easy nowadays to build your own GUI, so I did.
(I found it's still quite some work to polish it so that it's actually good. Therefore, sharing it could still benefit others, so I did: obeya.si, free, open-source)
Yeah I feel like a lot of us have reached this conclusion, I myself have also built a custom one for my use-cases as its fun to tinker.
There are tons available now in different flavours: t3code, herdr, cmux, paseo, happycoder – to name a few off the top of my head.
