Google Docs Updates Presentations With Real-Time Collaboration, New
Themes, Transitions and More Google Docs has rolled out a new version
of its presentations tool with over 50 new features, including,
simultaneous editing, a series of new slide… Read… Google Docs'
presentations module used to be fairly lackluster, but they've updated
it recently to make it more compatible with people coming over from
Microsoft Office, or people who want a more robust presentations tool.
If you're a fan of LaTeX, or just remember having to apply it for your
graduate thesis, you'll love Beamer. Where other presentation tools
give you a GUI where you drag in elements you want to use like images
and video and then tweak text boxes to include the information you
want on screen, Beamer requires you to build your presentation in a
custom markup language that works for just about any LaTeX document.
