LibreOffice自带的Math公式编辑器仅针对数学公式做原生适配优化，完全未适配化学专业书写场景，不符合化学学术规范与日常使用需求。
LibreOffice Math formula editor is primarily designed and optimized for mathematical formula composition, and it lacks complete native support for chemistry‑related writing and teaching workflows. Multiple notable usability issues exist for chemistry users.
First, all chemical element symbols are rendered in italic font by default. This contradicts established international academic standards for chemical notation, where element symbols should use upright roman type. Users have to insert the nitalic{} markup command manually for every single chemical element symbol one‑by‑one to get correct upright text. There is no global toggle or one‑click setting inside the Math module to disable automatic italicization specifically for chemical formulas. Repetitively adding markup for each element creates heavy redundant work for users writing long chemical equations.
Second, the built‑in symbol panel is missing many essential chemistry‑specific graphical symbols. This includes the reversible equilibrium arrow for chemical reactions, precipitation symbol, gas evolution symbol, as well as left superscript and left subscript glyphs required for isotope notation. None of these frequently‑used chemistry items are available as click‑able UI buttons. Users can only produce these symbols by memorizing obscure markup syntax and typing code manually, raising the learning barrier significantly for students and teachers.
Third, LibreOffice Math does not ship with an official built‑in template library for common chemical scenarios. Templates are absent for ionic equations, redox reaction equations, isotope marking formulas and other widely‑used chemistry formula types. Ordinary users cannot leverage ready‑to‑use one‑click templates and must memorize a large set of special syntax rules. This results in low writing efficiency and poor user experience for chemistry‑oriented document creation.
Expected improvements:
Add a dedicated chemistry‑oriented working mode together with an independent chemistry‑specific toolbar within the Math module. When this chemistry mode is activated: all chemical element symbols should display as upright roman font by default to comply with international academic standards. Add one‑click graphical UI buttons for all frequently‑used chemical symbols and isotope‑related notation elements. Deliver a comprehensive official template library covering chemistry formula use‑cases from middle‑school level up to university‑level content, including standard chemical reaction equations, ionic equations and isotope formulas.
Hello @nezhasantaizi,
Thanks for sharing the question already translated.
You can unmark Italic for variables.
Anyway, you can ask for an enhancement at https://bugs.documentfoundation.org/
