• [X] I believe this is a way to improve. I'll try to join the Continue Discord for questions
• [X] I'm not able to find an open issue that requests the same enhancement

Problem

It's not obvious what paste and cut options do when you right click in the Continue window as the llm's outputted text is immutable.

Solution

Remove the cut and paste options when right clicking inside the Continue window but outside the input box.
