Hello, im sorry for spam-like many feedbacks

## Many latex renderers have error detection feature.

## Examples

- when I mistyped
`cap`

as`cab`

(partially renderable)

```
\mathbb A = \{ \mathbb X_1 \text{ in } A_1 \} \cab \{ \mathbb X_2 \text{ in } A_2 \} \cab\cdot\cab \{ \mathbb X_n \text{ in } A_1 \}
All caps are mistyped as "cab"~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~^
```

- and when I made a typo from
`]`

to`}`

(unparsable).

```
\mathbb A = \{ \mathbb X_1 \text{ in ] A_1 \} \cab \{ \mathbb X_2 \text{ in } A_2 \} \cab\cdot\cab \{ \mathbb X_n \text{ in } A_1 \}
^~ Unparsable because of this typo
```

In “partially renderable” cases, all above renderers notified about the error with error point.

In “unparsable” cases, Overleaf & KaTeX provided useful clues about the error point.

## But supernotes does not have.

But in both error cases, supernotes just displayed raw code without any error message.

## So my feedback is

Plus to the uncomfortableness of typing LaTeX code using sans-serif font, hard LaTeX error finding experience discourages myself to write note cards.

I’ll happy if LaTeX typing environment is enhanced.

Thanks!
