-- Added a TsukiHime integration for downloading English (and Japanese) subtitles, mirroring the Jimaku flow: `Ctrl+Shift+T` (configurable via `shortcuts.openTsukihime`) opens an in-overlay modal with two language tabs (the first follows `secondarySub.secondarySubLanguages`, defaulting to English; the second is Japanese) that parses the current video filename, searches TsukiHime releases, lists extracted text subtitle tracks filtered by the active tab, then downloads the chosen track, decompresses it (requires the `xz` binary), saves it next to the video with a language suffix (`<video>.en.<ext>`, `.ja` for Japanese tracks, etc.), and loads it into mpv immediately - Japanese tracks as the primary subtitle, other languages as the secondary subtitle. No API key is required; also reachable via `subminer --open-tsukihime`, the `__tsukihime-open` keybinding command, and configurable under a new `tsukihime` config section. TsukiHime is the successor to Animetosho, which stops processing new releases in May 2026; it imported the Animetosho index and mirrors its attachment storage, so older releases stay reachable. Existing `animetosho`, `shortcuts.openAnimetosho`, `--open-animetosho`, and `__animetosho-open` inputs remain accepted as deprecated aliases.

 [TsukiHime](https://tsukihime.org) tracks anime torrent releases and extracts every attachment - including embedded subtitle tracks - from the release files, hosting them for direct download. SubMiner integrates with the TsukiHime API so you can pull English subtitles for the currently playing episode straight from the overlay, no torrent client involved. Downloaded subtitles are decompressed, saved next to the video, and loaded into mpv immediately.
 
-This is the English-side companion to the [Jimaku integration](/jimaku-integration): Jimaku covers Japanese subtitles, TsukiHime covers your secondary language (English by default). Releases that ship multiple languages (e.g. Netflix `[MultiSub]` rips) expose them all; the modal's tabs pick which ones you see, and each download is saved with its own language suffix.

 ## How It Works
 
-The integration runs through an in-overlay modal opened with `Ctrl+Shift+T` by default. The modal has two tabs that filter the subtitle tracks of the selected release by language: the first tab follows your `secondarySub.secondarySubLanguages` config (defaults to English when unset, and the tab is labeled accordingly - e.g. "German" if you configure `["de"]`), and the second tab is always **Japanese**. Tracks with no language tag stay visible on the first tab.
+The integration runs through an in-overlay modal opened with `Ctrl+Shift+T` by default. The modal has two tabs that filter the subtitle tracks of the selected release by role: the first follows `secondarySub.secondarySubLanguages` (English when unset), and the second is always **Japanese**, the currently supported primary subtitle language. Tracks with no language tag stay visible on the secondary tab.
 
 When you open the modal, SubMiner parses the current video filename to extract a title and episode number (same parser as Jimaku - `S01E03`, `1x03`, `E03`, and dash-separated numbers all work). If the filename yields a high-confidence match, SubMiner auto-searches immediately.
 
@@ -22,7 +22,7 @@ From there:
 
 1. **Search** - SubMiner queries TsukiHime with `<title> <episode>`. Results appear as a list of releases (e.g. `[SubsPlease] ... - 28 (1080p)`), each showing size, file count, and the subtitle languages the release carries.
 2. **Browse releases** - Select a release to list the text subtitle tracks extracted from its files. English tracks sort first; image-based tracks (PGS/VobSub) are filtered out.
-3. **Download** - Selecting a track downloads the xz-compressed subtitle from TsukiHime's storage, decompresses it, saves it next to the video (or a temp directory for remote/streamed media), and loads it into mpv. Japanese tracks are selected as the **primary** subtitle; any other language loads as the **secondary** subtitle, so your Japanese primary track stays in place. The filename carries the track's language - `<video basename>.en.<ext>` for English, `.ja` for Japanese, and so on - so mpv and media servers detect the language correctly.
+3. **Download** - Selecting a track downloads the xz-compressed subtitle from TsukiHime's storage, decompresses it, saves it next to the video (or a temp directory for remote/streamed media), and loads it into mpv. Japanese tracks are selected as mpv's **primary** subtitle. Tracks from the configured secondary tab are assigned to mpv's **secondary** subtitle slot without replacing the primary. The filename carries the track's language - `<video basename>.en.<ext>` for English, `.ja` for Japanese, and so on - so mpv and media servers detect the language correctly.
 
 Because releases on TsukiHime are the same files circulating as torrents, picking the release that matches your local file (same group, same version) gives you subtitles with exact timing - no resync needed. If your file is a raw or from a different group, pick any release of the same episode and adjust timing with the [subtitle sync tools](/troubleshooting#subtitle-sync-subsync) (`Ctrl+Alt+S`) if necessary.
