The interface below the menu bar is localized (618 fixed menu entries, ~490 panel rows) but an
effect's name still rendered in English everywhere it appeared: the generated Effect menu, Effect
Controls, the Timeline and Effects & Presets.
The registry's English name is the effect's identity: `effect.list`, `effect.apply {"effect": …}`,
scripts, expressions and the property tree's group name all match on it. Only the drawing changes.
`crates/ui-egui/src/i18n/effects.rs` keys the names by effect **id** rather than by the English
string — a repeat is stored as `Gaussian Blur 2` (an English key would miss it) and upstream
renames a display name now and then, while the id is stable. It carries 306 rows for Simplified
Chinese, one per effect in the registry, taken from the installed After Effects 2026 (26.5.0.89)
Simplified Chinese interface, with the `CC` series following Adobe's Chinese documentation (which
names 68 of the 69 that its interface leaves in English). `Cryptomatte`, `EXtractoR`, `IDentifier`,
`Key Light` and `Unmult` stay in English as brand names; `Face Measurements` and `Face Track
Points` are EffectCraft's own effects. The 21 category folder names are in the same file, worded
after the effect names (channel → 通道, noise → 杂色, matte → 遮罩 …).
What draws the catalog now:
- **Effect menu:** the entries and the category submenus. The command and its `{"effect": <id>}`
params are untouched, so the menu still applies by id.
- **Effect Controls:** the header, its Rename field, the accessible name and the About popup.
- **Timeline:** effect group rows, and the search (a Chinese interface is searchable in Chinese).
- **Effects & Presets:** the rows, the drag ghost, the folder rows and the search.
Kept as they are: the effect id, the property tree's `PropGroup.name`, every automation id and
label, `effect.list`'s `name`/`category`, and the undo label (`Apply Gaussian Blur`). A name the
user typed in Effect Controls stays verbatim, and a repeated instance keeps the index the engine
appends (`Gaussian Blur 2` → `高斯模糊 2`). No other language has rows yet, Traditional Chinese
included, so those draw the registry's English name.
Tests: nine unit tests under `cargo test -p effectcraft-ui-egui --lib i18n` cover the data (every
effect has a row, the row still carries the registry's English name, ids are unique, only the five
brand names repeat their English name, every category has a row, a row names an effect the registry
knows) and the behaviour (the instance index, user renames, English and untranslated languages,
search) plus a scan pinning the drawing sites. `crates/ui-egui/tests/ui_effect_names.rs` checks the
Effect Controls header, the generated Effect menu and that the ids, automation labels and
`effect.list` stay English.
`docs/localization-parity.md` and `docs/gaps.md` no longer record effect names as deliberately
English; effect *parameter* names are still untranslated and stay the next piece.
