I love that I can go as deep or as wide as I want on any subject.
Can't change the font size.
I'm a non-technical co-founder of an app to help small business plan and track all their advertising. I wear a lot of hats. I'm also a visual thinker.
I need to spread things out and see how they all fit together. I need to be able to see the big picture and then dive into the details and I need to be able to do that fluidly and frequently on a variety of subjects. I really wanted to be able to use my entire screen real estate for this purpose.
I remembered seeing Milanote on Product Hunt when it was an idea and not yet available. I signed up for it and happily paid for the upgrade. It's the perfect app for me and I use it every day.
The feature I like best is being able to upload links for the content I curate. When I'm ready to learn about a subject, I have great content to choose from and a place to write down my thoughts. I can add images and notes and go from subject to subject. I can clear out my email fast and that is worth the money alone.
I would suggest you try Milanote because it can make your life so much easier.
