Tab Scissors and Tab Glue
While it may not be a huge deal to pull off one or two tabs and resize them to allow side-by-side browsing views, Tab Scissors and Tab Glue make it a one click process. When you are dealing with multiple screens (or a screen and a projector) these two extensions become your best friends!
Try out these two free awesome extensions! I’ve even had my students install them on their Chromebooks so that they can following along with my presentation while taking notes much easier.
