I track my previous smokes using this site's VH and the "Smoke One" function as well.
However, I immediately move them from the "Previous Smokes" humidor to an active humidor I created called "Previous Smokes." I do this so I can periodically clear this out by exporting to Excel and then deleting its contents (basically, delete the humidor and create a new one after export). This allows for multiple entries of the same cigar with different dates. Another way to accomplish this is to add $0.01 to the cost of your cigar so it forces a unique entry in your previous smokes (or any other humidor for that matter).
I chose to use a date format, in the notes section, like this: YYYYMMDD. This makes it easy to sort and maintain once exported to Excel. I also enter the location of where I smoked the cigar and any other pertinent information, like who was with me, etc. The next line of the notes field is always my tray location (for keeping track of my stock) and subsequent note lines are used for box codes or the name of the person who gave me the cigar in the case of a gift.
While this seems tedious, it really isn't. I create a new Excel workbook every year to record that year's activity - an electronic journal of sorts.
Here's a sample of what my Excel data of previous smokes looks like:
VH Name------------ Vitola Detials----------------------------------------------------------- Qty Purch Date Age Cost Notes---------
9.5 Previous Smokes Oliva Serie V Maduro Especial 2014 Double Toro, NIC (6 x 60, NIC) 1 10/24/14 2 Days 9.15 20141024 LL / C1

9.5 Previous Smokes Pinar del Rio Liga Especial Reserva Superior Gran Toro, DR (6 x 54, DR) 1 4/5/13 569 Days 7.15 20141012 Rutger's Garage / B3

Since the note column always starts with the date, it's easy to sort. The gifted cigars above have 0.00 value and since they were smoked when gifted have no age. The rest of the notes are a bit cryptic - my shorthand for where I smoked them and the location within my humidors from where I pulled the stick.
