Folders Folders Folders

Is there any plan to add folders to the program? I have some groups of projects that are related and would like to group together. I know I can have multiple pages on one project, but once I get past 5 to 6 pages, my computer starts to slow down. It would be much nicer for me to work on projects with few pages and have the option to group projects together in a folder. I know this has been posted a number of times. I am not seeing a recent answer.
