A Great Tool for Research
I spend most of the day online, and I use Vivaldi all day even when I am working on my books or website in Serif PagePlus or WebPlus.

By tiling as a grid, I can refer to the Pali text, its Commentary, a translation, and the Pali English Dictionary in one Tab Stack. By saving the tiled tab stack as a session, I can reload it later, or modify it and save the new session for working on a different translation project.
