Absolutely blown away by the features and customization options for this planner. It truly lets you build your dream planner! So well thought out and designed. I hated having to switch back and forth between files on my reMarkable. Now I have a planner and notebook that I never have to exit, because everything is in one place and well organized. The hyperlinks are so well done! I will come back for this one next year for sure! I would love the addition of some copy and paste stickers in the future. I was able to get some of those elsewhere and build a sticker section into the planner. But it was a bit time consuming. Would love to have this included one day. Highly recommend this planner!!! Well done!

the PDF's work well with my Onyx Note Air, and they are easy to edit and mark up. The tool for customizing is great with a ton of options.
