## Remember the cursor position in each file for the next editing session.
set positionlog
The flag was there since 2011, but I only started to enable it a few months ago. Pretty nifty feature, although it took me some time to get used to the new flow.
Vim's 'return me to the last location in this file'[0], however, is great when repeatedly editing large config files in this same place.
Nano should try to implement it, if it hasn't already.
