 Slideshow presentations usually suffer from a lack of a second projector displaying the previous slide. A brief moment of thought is enough and you don't read the last sentence on a slide before it disappears. Of course, hand-written online teaching suffers from the same problem if you use a single page that is periodically cleared. Common formats of computer screens suggest showing two portrait pages side by side. This is what Sauklaue does.
 
-Furthermore, an external graphics tablet can be mapped to only the currently active of the two pages. This way, you can write twice as big (in area) as you would otherwise, which generally improves handwriting.

 Normally, the two columns are "linked": They are forced to always display consecutive pages of the document.
 
 With the "unlink views" button (below the pen size buttons), you can unlink the columns. You can then independently change the displayed page in both columns. This can for example be useful when you want to remind your audience of something mentioned earlier, while still showing the most recent page.

 If you want to give a presentation created with the LaTeX beamer package and "animations" (`\pause`, `\uncover`, etc.): Try including it with "Insert PDF file (by label)". You should see every frame in its first state (before the first `pause` command). Use "Next PDF page" to uncover more text on the current page (up to the next `pause`). Anything written on the current slide will remain visible when you do this.

 This is not implemented yet, but as a workaround, you can import a PDF file with empty pages of the correct size.

 Make sure that before starting Sauklaue, the tablet is mapped to the bounding box of all screens, not just to one screen. (For example, for the XP-PEN tablet, load the driver and make sure to set the mapping to "AllScreen". Sauklaue will manipulate the mapping assuming the internal setting is "AllScreen".)
