If your project has a lot of plan pages or boards, it may become overwhelming to see them all at once and difficult to navigate to the right one. You can organize the pages by creating stacks of pages and naming them. You can create a stack of pages by simply clicking to drag one page on top of another, creating a new stack.

You can then rename the snack to something meaningful such as "Kitchen Elevations" or "Cabinet Shop Drawings" or "Inspiration Boards" by hovering over it and clicking the "Rename" button. The second way to create a new stack is by creating a new, empty stack via clicking the page adder (the red button on the far right) and clicking "New Stack" and then dragging pages into it.

To see a stack's contents, you can click on it to expand it. Click again to close the stack.

To remove a page from a stack, drag it out of the stack. It will be placed back at the top level of your project next to the stack it came form.

To combine two stacks, simply drag one onto another; the name of the receiving (or destination) stack will be kept for the new, combined stack.
