Because it's quite a common CSS property.

We need triggers like "scroll into view", "while scrolling in view", "mouse move over element" for desktop. For example for 1) revealing objects when entering the viewport 2) parallax effects 3) smooth bending/moving of the objects along the XYZ axis while moving the mouse in viewport or over the element.

Being able to nest components inside components, allowing creation of more complex components

Similar to Adobe XD functionality, a checkbox for containers or shapes that makes everything underneath it blurred.

For instance, you can't set a sentence in bold and another one in regular within the same layer. We should be able to apply different formatting options within the same text layer in order to lower the number of layers to create.

I would like to propose being able to underline text. Underlined text is frequently used in design (particularly web) to show an interactive link. It would be very helpful! Thank you and loving ProtoPie.

While moving objects around, they are often placed on subpixels (not sure if that's the term but X = 280.19; Y = 704.83). That means I have to go in and manually fix in all the numbers before I start adding triggers because I'd like to have triggers detect on whole pixels. If there was a 'snap to pixel' button, it'd take that manual step of rounding up/down the numbers myself every time I position something.

The ctrl + x command does not work, which cuts the object. You have to copy the parent, paste the copy from the right place, and delete the parent.
