UX - Buttons / Menus

Hello.

As i read FireCoder is in its early stage. Maybe it is the perfect time, to give some suggestions what could improve the usability of FireCoder. These things would be nice:

- a copy button, to copy the generated code-text
- a cancel / stop button to stop the ai commenting more text, because the code is finished but the AI explaination has a too long text
- a drop-down menu where we can store the chats (with the possibility to delete them by a small X-button)
- a mouse-button rightclick context menu, when selecting code inside the VScode editor. Inside such a context menu
could be something like: analyze code, find problem, reformat code, etc. This could be send back to FireCoder and it will
automatically start the chat.
- Start / Stop Server Button: Because sometimes i dont need FireCoder. And if i am not able to deactivate it, my RAM is full. So deactivating the Server manually would free RAM space
[EDIT: When starting VScode, the server should not start automatically. imho. But this could be handled as a own preference by the user inside the FireCoder Settings ]

I think these few things, by adding some "Buttons" and "Menus" could improve the usability of FireCoder.
