There is one (known) thing that's in the markdown spec but trilium does not support: tables. (And it's actually in the spec.) Math expression in markdown does not come for free. They depend on MathJax or other TeX math expression render libraries. (Not to mention that $ ... $ is also an extension -- a lot of libraries actually expect \( \) and \[ \] for inline- and block-level expressions. But that would be another issue.)

However, it is a huge pain to re-type all math expressions. Poking around in the code suggests we could start here to add math expression import.

You can try to import your markdown files with trilium-py. It will handle your Latex equations.

Unfortunately, the \and symbol seems not recognized by the library used by trilium.

Hi. I've managed to get the things going. But there is a catch: \and is actually a predefined macro that is not a part of standard TeX. The "proper" way to typeset this symbol is to use \land (or to be more pedantic, \wedge). I haven't figured out how to add custom macros to KaTeX used by Trilium yet.

@dousha 0.61 has a new markdown library and table import works. However, I don't believe tables are in the CommonMark spec.

yeah,now I've changes every \and \or into \land \lor , thx!
