What's New in 1.3.0
• Redesigned interface: cleaner, more focused screens across the Decoder, History, and Settings tabs.
• Try it faster: tap example codes right in the input field to see decoding in action without typing.
• Clearer results: your freshness call (Good, Usable, Check, Replace) is front and center, with the full decoding breakdown tucked into an expandable section so results aren't buried in detail.
• Easier-to-scan history: saved codes now show freshness and format status at a glance, with a clear badge when a code has more than one possible date.
• Reorganized Settings: freshness thresholds, decoder preferences, and data management are now grouped into clear sections.
