Uh, it sounds like you're having trouble understanding that people in this thread are talking about two wildly different "claude code" applications. Those who are claiming the resources issues don't apply to them are referring to the cli application, ie: `claude` and those are saying things like "Just open both apps..." are surely referring to their GUI versions.
No, I've never used the GUI version. I literally just had to close and reopen the terminal running the Claude Code CLI on my Mac yesterday because it was taking too many resources. It generally happens when I ask Claude to use multiple sub agents. It's an obvious memory leak.
