Can't open the second page any more than approximately 30% of the window. Useless.

WHY is this functionality so freakin' hard to implement!?!?

Cool feature that helps me do my job. I can keep my equipment monitoring screen up with my ticket que on one "page".

I would like to see the ability to have an auto refresh and have both views be equal width (50:50).

I can't get BBC iPlayer to play in side view :-(

Just perfect

Just cannot use a browser without this. Amazing.

Ausbaufähig. Die Ansicht einer Seite als Sidebar ist zwar nett, nur leider werden automatische Reloads/Aktualisierungen nicht übernommen, und ein F5 funktioniert auch nicht.

It's a fantastic tool, please improve it! For example loading bookmarks directly in side view or a bar on the left with bookmarks (icons) to open directly in side view.

It is convenient to be able to open another browser at the same time in one window, but I want you to be able to enlarge the frame size further and return to the previous page. It will be okay if it improves even it. (I'm using a translation machine)

it looks promising, but the way it works now it looks like the poor man's version of Vivaldi Panels

nice... work by mozilla team...
