Colour selection seems fixed.

Check boxes look much better.

The margin on the Lines template shifts across the page every time one scrolls left or right (in screenshots, scrolling right)

By the same token, checkboxes are only visible if scrolling up or down from the opening page.

Maybe it's easier for you to set Penpen up so that left sided markings (margin, checkbox) only render vertically from the opening page ?

Users who want to use a margin might find it easier to scroll around or view the export image of a note that has only one margin, rather than multiple ones.

Thoughts, anyone ?
