[Enhancement]: add button null & Expand Clipboard

[july702]

Describe the issue

I have two ideas for improving this process:

Add a button next to copy and paste that sets the copied object to NULL: This would allow you to easily clear the copied object if you accidentally copy something you didn't intend to.

Expand the Clipboard to Clipboard History to keep more results: This would allow you to store a history of objects that you've copied, so you can easily access them later without having to constantly recopy them.

These are good suggestions that could potentially improve your workflow and save you time.
