+10 for OneNote, especially if you use a modern pen-enabled computer. This may be the best product Microsoft has - it's without question the only reason I pay for an annual Office license. It's a real shame OneNote doesn't get the quality development attention it deserves anymore (the best version was back around Win 8.1). (How about some killer assisted sketching, or at least open up an API for third-party extensions for things like drawing/sketching? A combo of uMakeand a more advanced version of Catchbook embedded into OneNote is my dream app...)
