The required interface when giving a presentation is different than when reading a paper or a book, or when reviewing homework or collaborating on a paper.

I therefore suggest a dedicated whiteboard (or presentation) mode (while allowing the option of creating additional modes). The following is a list of features that I imagine in the whiteboard mode:

1. For FullHD aspect devices, e.g. 16:9, and 16:10, the toolbox should be placed as a vertical column.


2. The contents of the toolbox should be user selectable. Here are a few shortcuts that I'd like to see in the such a toolbox:


3. pen size and shape. E.g. 3 pen sizes.


4. pen color shortcut by color button. One option (fixed) should be a palette button, which can contain additional presents (like now).


5. Size and color button (like now) optionally.


6. Add shape (ellipse, rectangle, rounded corner rectangle)


7. Add page button

I'm sure others come up with additional suggestions.
