I have used Onenote extensively as a teacher to organize my teaching materials. I use it all day long. We've had to move to the online version today and I am very sad to see some of the features I used all the time are not there anymore. I agree with others that the lack of being able to customize tags is a huge loss. I used the clipping tool all the time, but don't see that anymore. I used to clip materials and paste them onto pages very easily with the clipping tool. Being able to customize a page by pasting an image on the page and then setting it as a background was something I used a lot - made all sorts of templates to write on top. And the one that I'm really missing is the ability to drag rows on a table into different orders. Now it looks like I have to cut and paste rows if I want to move them around, which I used to do all time. Visually, I'm finding the sections/pages tabs on the side too large. I'm constantly having to show/hide pages. It was much easier to navigate when the tabs were on the top. I loved the desktop version because I could customize so many things. I raved about it to all of the colleagues. Now, the online version is okay, but it feels like a pre-packaged program. Being able to have customization options is really what used to set notebook apart.
