 ## [1.2.6b1] - Unreleased
 
 ### Added
+- **Open a File Manager model in your desktop slicer, and pick which one from the 3D preview (#2725, contributor @pascalheidmann)** — The **Slice** action on a file card only existed when the optional slicer sidecar was running. Turn the sidecar off — which is the default, and how most installs run — and the File Manager offered no way to get a model into a slicer at all, even though the Archives page has handed files to a locally-installed Bambu Studio or OrcaSlicer over the URI scheme for a long time. The File Manager was simply the one place that never got it. **Slice** now appears on every unsliced model (`.3mf`, `.stl`, `.step`, `.stp`) in both the card menu and the list view, and does whichever of the two things your configuration means: with the sidecar on it opens Bambuddy's slice modal and the work happens on the server, and with it off it hands the file to your desktop slicer. The icon says which you will get before you click — a cog for server-side slicing, an external-link arrow for the handoff — and which slicer receives the handoff comes from **Settings → Workflow → Slicer → Open in Slicer**, falling back to the preferred slicer as it always has. The 3D preview goes further, because that is where you are actually looking at the model and deciding: its slicer button is now a split button, and the chevron beside it offers the alternatives without changing any setting. With the sidecar off that is the slicer you did *not* pick as your desktop target; with it on, the primary button still slices server-side and the menu offers a one-off desktop handoff to either slicer. Two things that used to be silent now are not: a handoff refused for want of permission raises an error toast rather than launching the slicer at a URL it cannot fetch, where a permission problem looked exactly like "no slicer installed"; and the file-type rule is shared between the card menu and the 3D preview, so a file can no longer offer **Slice** in one place while showing it greyed out in the other. Permissions follow the endpoint each mode calls — the handoff is a download and needs the same library read permission that lets you see the file, server-side slicing writes a new file and needs upload rights — and the action is shown disabled with the missing permission named rather than hidden. Translated in all locales; wiki updated. Covered by frontend tests.
 - **Temperatures on the streaming overlay, and a builder for its URL (#1422, reporter @SMAW)** — The overlay at `/overlay/{printer}` draws live print data over a full-screen camera view for OBS, a wall display or any browser source. It could already be tuned — which fields, what size, what frame rate — but only through query parameters documented in the wiki, and temperatures were not among the fields on offer. Both are now addressed. Nozzle, bed and chamber readings join the list, shown with the target while the heater is still climbing and with the target dropped once it is reached, so a settled hotend reads "220°C" rather than "220 / 220°C" for the rest of the print. Both nozzles appear on a dual-nozzle printer. They are drawn whether or not a print is running, since a preheating machine is exactly when they are worth watching, and each reading appears only when the printer genuinely reports it — chamber temperature stays absent on P1 and A1 models, which publish a value with no sensor behind it. And **Settings → API Keys → Streaming Overlay** now builds the URL for you: pick the printer, tick the fields, set size and frame rate, paste in a token if login is enabled, and copy the result, with an optional preview alongside it. The preview stays off until you ask for it so that leaving the settings page open does not hold a viewer on the printer's single camera connection. Making that preview possible needed one narrow change to the security headers: the overlay path now sends `frame-ancestors 'self'` instead of `'none'`, so Bambuddy's own UI can embed it. Every other page still refuses to be framed at all, `'self'` permits a framer only on this same origin, and embedding the overlay from another host — Home Assistant on a different port, say — is unchanged and still requires `TRUSTED_FRAME_ORIGINS`. Temperatures are not in the default field set, so an overlay URL already pasted into a scene looks exactly the same after upgrading. Translated in all locales, wiki updated, covered by backend and frontend tests.
 - **The external spool can be hidden from the printer card (#1782, reporter @Arn0uDz)** — An external spool holder that never gets used still occupies a full card's width in the **Filaments** row, next to the AMS units that are actually being used. An eye icon at the right-hand end of that row's header now hides it, and clicking it again brings it back, so nothing is lost behind a settings page you would have to remember. The choice is remembered per printer and stored in the browser, like the card size and the offline-printer filter — one machine in a fleet can be tidied up without touching the others, and nothing changes for anyone else using the same Bambuddy. The icon is deliberately absent on a printer with no AMS: there the external spool is the entire filament section, and hiding it would leave an empty row. That guard also covers the case of an AMS being unplugged from a printer whose external spool was hidden earlier — the spool reappears rather than leaving a blank row behind. On the H2D and H2S both external positions share one card and so hide together. Translated in all locales, wiki updated, covered by frontend tests.
