Security of unselected items when CodeBook is unlocked

Hey there. I love CodeBook! <- preface

I was recently mumbling about where to store private key backups for crypto wallets, digital signature certificates etc. I know that the strongest practice would be never ever keep those data in digital form and on any cloud (I guess you might agree but let me know…).

Anyway let’s suppose I store a private key or some very sensitive info which I won’t access frequently in CodeBook, question is: since I use the app a lot for my other daily tasks, is unlocking Codebook a “threat” for all stored data even if that specific record is not being displayed on screen? In other words: should I consider keeping very sensitive info which is not accessed frequently separated from not-really-sensitive info used everyday?

cheers.
