I enjoy making books. Working out how many blank pages I need so the whole thing folds and flows properly is easily the most painful part of the process. And I'm too cheap to buy imposition software.
My bookbinding spreadsheet only takes me so far, so I made Folio Maniac. It plans signatures, estimates the book block's thickness, and arranges the PDF pages for printing and folding. It's free, runs in your browser, and your PDF stays on your machine. No upload, no account.
It's also very much a beta. I'm still testing it with my own projects, and the print layout needs more real-world testing. Check your paper measurements and print a single test sheet before committing a whole ream. Printers already have enough ways to ruin your afternoon. Running amok tops the list.
The article includes screenshots and a link. If you bind books, I'd love to hear what it helps with and what it gets in your way.
One last note: this isn't commercial software, and it doesn't track anything.
