Hello Artur, hello Jarek,
thank you for your feedback! I actually have a blind tasting feature on my upcoming roadmap. The premise for this was to allow you to taste a rum multiple times (without overwriting the previous tasting). This functionality is now implemented in the new version in the form of a tasting history. You can now see how your personal taste and rating change over time.
I will then probably tackle the blind tasting feature at the beginning of the new year.
