Bug fixes

- Clearer warnings for unsupported files in convert modes: Convert 1:1 and Convert Structure now tell you when an attached file is not a PDF or PowerPoint and let you remove it before continuing, instead of failing partway through with an empty course.

- Titles with ampersands and symbols display correctly: Course, module, and lesson titles that contain an ampersand or other special characters no longer show raw code such as & to learners or across the library, editor, PDF, and preview.

- Feedback button stays reachable with a side panel open: The feedback button now moves aside when a side panel is open, so it no longer sits hidden behind the panel.

- Corrected Estonian interface translation: Fixed an inaccurate Estonian interface translation reported by a customer.

- No more empty lessons when converting slide by slide: Converting a PowerPoint or PDF slide by slide no longer produces empty lessons that could not be published.

Improvements

- 9 more interface languages: The course interface is now available in nine more languages: Greek, Romanian, Bulgarian, Serbian, Croatian, Slovenian, Turkish, Korean, and Czech, so more learners can read your course in their own language.
