Visual menu with formula templates in LaTeX block like in OneNote and MathType.
Adding a menu with groups and buttons for each specific function with an icon instead of a list with commands.
You don’t have to memorize every command you need. Much easier to navigate. Writing formulas is accelerated several times, there is less chance of making a mistake. For students/pupils: At lectures, you will be able to write formulas in time, because instead of writing a whole command, it will be enough to press one button. Without this feature, writing on a piece of paper by hand is much faster than writing commands in a block.
Handwritten equations in LaTeX (this is a tricky feature and doesn’t always work even in OneNote).
