Add more functions to the "Right Click" button on a Tab

Hello Xmind Team,

In Xmind 8 desktop version, the "Right Click" button on an Tab just allows one function which is "Close".

I suggest enhancing this by adding more functions like:

- "Copy" / "Paste" so we can easily duplicate/copy a mind map

- "Edit Options" so we can edit the specific preferences of the actual mind map

- "Export To" so we can export it to another format

Are you planning on adding functions like these to Tabs?
