KeyType Pro

- Fixed keyboard activation status : Removed the old read-and-clear logic, so the status no longer flickers between active and inactive. - Improved activation detection : Added a file-based backup in the App Group shared container, making detection more reliable when NSUserDefaults has sync issues. - Updated category name : "语言学" renamed to "IPA辅音" in the Chinese category data.

What's New Recent Symbols on the "Frequent" Key The Frequent button now opens a panel of recently used characters instead of a static default list. Reverse-Chronological Order The most recently used symbol always appears first. Deduplication Tapping a symbol that is already in the recent list moves it to the front, so duplicates are avoided. Persistent Storage Recent symbols are saved to NSUserDefaults via the App Group, so they persist across keyboard sessions. Default Fallback If no recent symbols exist yet, the panel still shows a sensible default set of common symbols.
