Ok, thanks.
And is it me or are the notes not 'relatable' to some specific text position?

Yes, I know. My question was about the notes (not the annotation stuff), because in notes one can write latex. However notes to an item are just collected and not related to a specific line of text / subsection etc. So this does not help when commenting on specific regions in the text. A workaround is to enumerate the notes and put number annotations to the text...

I second this. I am doing research and read pdf papers all the time. It would be extremely useful to be able to directly annotate the pdf with latex script and show up as nicely displayed math equations.

A work around I am using right now is to open pdf outside zotero in a paid software called PDF Annotator, which supports equations text box in latex (and a lot of other useful annotation tools).

Second this as well. Would boost the note taking experience in Zotero. Being able to discuss a specific mathematical term in notation is much more convenient than having to name it every time in the annotations (which I use much more than the notes).

This would be extremely useful if implemented.

eighthed!

+1 for this — it would make a huge difference for annotation-based note-taking.

My use case: I read technical (CS/ML) papers and write structured notes directly in highlight comments — truth tables, short derivations, comparisons of definitions. These really need GFM tables, inline/display LaTeX, headings, lists, and bold/inline code. At the moment the annotation comment popup is plain text only; even hand-written tags are stored and shown literally. The standalone note editor does support tables and math blocks, but moving everything into one long item note loses the lightweight "tap a highlight → read the note in context" workflow, and a single note containing dozens of annotations quickly becomes hard to navigate.

Feasibility has already been demonstrated by the community: the third-party add-on "Zotero Annotation Markdown" (https://github.com/qrkks/zotero-annotation-markdown) renders Markdown and KaTeX in reader annotation comments and in the page annotation popups on Zotero 9/10, while keeping the stored comment as plain-text Markdown source — rendering only, with source-on-edit and a plain-text fallback. It shows both the demand and a low-risk UX pattern, with no data-model migration required.

Why native support matters: add-ons are desktop-only and cannot run on iOS/iPadOS, as the team has noted, so comments written with Markdown currently appear as raw source on an iPad. Native rendering — even of just the common subset (headings, emphasis, lists, GFM tables, inline code, inline/display math) in the reader popup and sidebar, consistently on desktop and mobile — would close this gap.

Thank you for all the great work on Zotero 10 — the new Reading Mode is wonderful. I'd be happy to provide more details or help test if that would be useful.
