I have a notebook called "Useful Stuff" in which I put things I keep forgetting and for storing bits of useful code. I would like to keep this notebook in the list of notebooks that appear when you click on File in the top toolbar. I think this was possible in the past. How do I do this? At the moment it gets pushed off the bottom of the list, and lost, when I open more notebooks.
Also, I like a long list of Recently Opened Files (I keep the last 30). I have set this in the past but now can't find where you set this option. (I need to put how you set it in the "Useful Stuff" notebook!)
This post on managing Recently Opened Files is also relevant.
I find looking round the Global Preferences, where I assume this is set, difficult.
