found some linguistic (and layout) issues while checked quickly, other than the features in the instruction.
Description issue: redundant word
Repro step: VIEW > Immersive Reader, click Grammar Options
Correction: remove 2nd "現在"
Description issue: incorrect as Japanese ("指摘する" is not correct in the context (for 'like')
Repro step: click HELP IMPROVE OFFICE on the status bar (not WORD specific)
Suggestion: NA
Repro step: VIEW > Immersive Reader, click Text Preferences
1. Increase Spacing
Description issue: weird translation for 'Increase'
Suggested translation: "拡げる", "空ける", or something like that
2. font name
Expectation: Japanese font name should be listed (as well?)
3. layout issue
Expectation: the alignment should be the same as the English version
