Thanks for the reply BurgersNFries. Maybe it would become a priority if it was a small amount of extra money... I'd pay an extra $5/yr to be able to mark a notebook as encrypted. It's OK if that encrypted data is not indexed... It can be made understood to users that anything in the encrypted notebooks will not show up in search results. I would sit down and:
1. Tally up the number of Evernote premium subscribers.
2. Conservatively estimate the amount of development time, as well as time for updating help documentation, entering the extra password in the mobile apps, etc.
3. Run the numbers at 10% of Evernote Premium users paying the fee for "Evernote High Security Notebooks".
4. Also factor in the number of users who might be on the fence about paying for Evernote who will be pushed over the edge by this new feature. I realize this is hard to calculate but I'm sure the number is greater than zero Actually, I know it's at least one from Jpetroski's post above! These are brand new paying customers, this number can add up quickly.
I realize that you are an evangelist but to change priorities you have to show the business value. Maybe it's not there? Maybe they don't want to charge any "add-ons" to keep the pricing simple, in that case they need to put some serious effort into estimating #4 above.
At the end of the day, this feature will come to Evernote. The question is, when will it come and how much money is it costing Evernote to not have this feature?
