Tuning the editor
Width, spacing, text sizes, math rendering, and spell check.
The editor's feel has its own corner of Settings, under Editor.
Width and spacing
Editor Width runs from Super Compact to Super Wide. The Markdown appearance group carries the finer dials: block spacing, line spacing, letter spacing, and separate font sizes for body text, code, and math. Some surfaces still run on their own built-in metrics, so expect these to reach further as the rehaul settles.
Math
Render math is on by default and typesets LaTeX-style equations as you read them. Turn it off and they stay as the raw source you typed.
Math Font Size applies to the typeset result, from 14px to 20px, independent of the body and code sizes.
Spell check and fonts
Spell check is on by default, with a language setting offering English, German, Spanish, and Norwegian. Changing that language takes effect the next time Mnemo starts.
Typefaces are not user-selectable. Mnemo ships its own set: one for the UI, a matching monospace for code, and a dedicated math face for equations.
