Many thanks for catching these and providing the clear descriptions for fixing them. Much appreciated!

Version 0.0.9 provides a custom output setting in the settings panel to customize the way tab links are copied to the clipboard.

This version fixes many bugs, including the ability to paste tabs when only a new tab is open. It also adds a new options / settings page, and disables the total tab count badge on the icon by default. It also adds a new feature that allows you to move the current tab to a specific index position. Hope you like it!

This new version is the first attempt to port to the web extension API. There may be a bug when pasting that results in multiple copies of the same tab being opened.
