Is there any software like that? [aslt]

$\gdef\gerby{\href{https://gerby-project.github.io/}{\color{#c5000c} \text{Gerby}}}$

$\gdef\katex{\href{https://katex.org/}{\color{#329894} \KaTeX}}$

$\gdef\obsidian{\href{https://obsidian.md/}{\color{#a78bfa} \text{Obsidian}}}$

$\gdef\forester{\href{https://www.forester-notes.org/index/index.xml}{\color{#00B770} \text{Forester}}}$

$\gdef\typst{\href{https://typst.app/}{\color{#239dad} \text{Typst}}}$

  • $\obsidian$ looks great and has a rich ecosystem of community plugins, but I’d really prefer if it could:

    • Not break the rendering of normal $\katex$ formulas I write.
    • Support drawing non-rectangular commutative diagrams.
    • Provide theorem environments or something similar.
    • Be lightweight — my disk space is running dangerously low from all the Electron-based apps I’ve already installed.
    • Work well on mobile devices with the help of a terminal emulator like Termux.
  • $\forester$ looks great, but …

    • I’d prefer to write in Markdown and $\typst$.
    • I want an out-of-the-box dark theme, and vector graphics rendered by the application should also have their colors properly adjusted.
    • I’d like a table of contents that’s always available, even on small-screen devices.
  • $\gerby$ looks great, but …

    • I don’t intend to write in $\latex$.
    • I can’t fully accept the tag system.
