Long time Evernote user - Questions

Hello, Frank.  Fellow Ex-Evernote Enthusiast.  I've run into many of the same problems with the transition to OneNote, so maybe I can help a bit.

1.  Search - Yep, the notebook has to be open before it is included in the Search.  Conventional advice is to 'have a notebook for everything."  However, as you've noted, this cripples the search.  I've gone with a single notebook approach, based on time periods.  Right now, I open a new notebook every quarter, and then close out the one for one year past (example: At the end of September I will open a 2018Q4 notebook and close the 2017Q4 notebook.)  Still limiting, but it's better than having to figure out which notebook I put that great SharePoint time saving tip in.....

2. Mobil sync - Yep, thus the single notebook. For mobile access, I find that the last quarter is usually sufficient for things I want at my fingertips.

3. Renaming - MS OneNote really, really does not like renaming notebooks.  I've lost data when trying to go back and make file names consistent.  I would not do it if you can avoid it.

4. QuickNotes - By default, they go to a semi-hidden notebook called, wait for it, "Quick Notes."  What I prefer is to create a tab (i.e., Section) that displays across the top called QuickNotes.  I then go into options and set all of the "Send Tos" to that section. Essentially, this becomes my In Box.  The only thing I do with pages in the In Box is make annotations so I can find them later (Project Number, Actions, etc.)  I then move it to my current period notebook.

Heads up: OneNote is way behind on Tags. In fact, ON Win10 has yet to roll out the promised 'tag search'.  Until that happens, I cannot make the move to ON Win10.
