Preview Text Size
Larger or smaller text in the Hermes Desktop file preview pane: scales the rendered Markdown from 90% to 175%, independent of Chat Text Size and UI Scale, through a row in Settings → Appearance, three command-palette entries and rebindable shortcuts (⌘⌥=, ⌘⌥-, ⌘⌥0 on macOS; unbound by default on Windows and Linux, where Ctrl+Alt is AltGr). The Source and Diff views keep their size.
Good to know before installing
Desktop-only (desktop/plugin.js inside the plugin SDK surface); appends one stylesheet that sets CSS zoom on the preview's [data-preview-markdown] element, removed on disable, so a Desktop release that renames that attribute turns the plugin into a no-op; stores the chosen size in plugin storage; no network calls, credentials, shell commands, background processes or telemetry.

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install preview-text-size - Said no? Turn it on later:
hermes plugins enable preview-text-size - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
