simple copy url button or custom button?

In my particular case, I need a button for copying the current URL for sharing. I know it's easy to copy URL from the address bar, but I think that may carry some custom parameters in URLs and that causes some trailing parameters and users sometimes copy incorrectly.
Also, we need the option to use some custom buttons eg. WhatsApp and only show it on mobile as this project does https://github.com/kriskbx/whatsapp-sharing/
I think it would be great if we have following things:

1. Custom icon or image to choose for the network or some custom task(e.g. copy URL).
2. Callbacks when the button is clicked for support of other networks besides existing ones.
3. Config option to specify if we want to use font-icons or SVGs provided by social_share_button.

Please add the copy URL button? For e.g. if a user copies the URL from paginated page etc then I would want the user to have the base URL in clipboard or what if I decide to use shortened URL for sharing by some method etc. in all these cases copy URL to clipboard option is great, it should copy the URL and tell user that he has the copied URL in its clipboard which can be shared.

This would be so nice to have included by default.
