Clicking on edit series should open a new tab.

[bloodyWriter]

The Button Edit under the Table of Contents should open a new tab and switch to that. For editing multiple Chapters you otherwise have to open it manually / go back to edit series.

You can right click to open it in a new tab.

 

[Piisfun]

Or middle click, which opens it in a new tab without having to click on an entry in the context menu.

Still would be nice to do it by default, though.

 

[LuoirM]

Or Ctrl Left Click
