Whenever you design a board, Folloze displays a mini-preview of the board’s look, which highlights the area you are working on in a yellow frame. The mini-preview automatically updates when you make design changes – even if you haven’t saved them. To make changes permanent, you must save them. 

While the mini-preview is useful, it doesn’t completely capture how your background image will look to viewers, as it is not a full-size display.
For a full-size display, click View Board in the top right. This opens a preview of your board in a new browser tab, showing you exactly what viewers will see. Unlike the mini-preview, the full preview only updates once you save your latest changes.
