Provide ability to select multiple tabs in order to link simultaneously with one click.
One example:
I use separate layouts to study individual Bible books. So I want to open many commentaries in one window or more, using only one panel per window. So I have many tabs (in one panel, one window) that I want to link together at once, but I can't. I have to link them all one by one.
I would love to be able to select multiple tabs that I can link at once, to save me much time and excessive mouse activity.
