Round-trip a raster preview through the DWG's embedded preview slot and
surface it to the OS file managers, so drawings show their contents in
Explorer / Finder / Nautilus instead of a generic document icon.
OCS:
* io::thumbnail — rasterize the scene to a BMP DIB on save (embedded via
acadrust's new Preview type) and read it back on open for the Start
page recent list; `--dwg-thumbnail IN OUT SIZE` CLI extracts a badged
PNG for external thumbnailers.
* io::file_association::install_thumbnailer — self-install the OS
integration on startup: Linux writes a .thumbnailer + hicolor mimetype
icons; Windows registers the IThumbnailProvider DLL under HKCU.
Shared core:
* crates/dwg-thumbnailer — lean (image-only) preview extractor + the
`badge_dwg` full-width "DWG" band, used by every platform so the
ribbon is single-sourced. Ships an rlib+staticlib.
* crates/dwg-thumbnailer-win — IThumbnailProvider COM in-proc server
(cfg(windows), CI-built as a workspace member).
* macos/ — QuickLook thumbnail extension (Swift + C-ABI bridge to the
core staticlib), assembled into a .appex.
Icons & packaging (single SVG source -> per-platform assets in CI):
* assets/mimetypes/image-vnd.{dwg,dxf}.svg — themed file icons.
* packaging: WiX ships dwg/dxf.ico + the thumbnail DLL and points the
ProgIds at them; Info.plist gets CFBundleTypeIconFile + the QuickLook
extension in Contents/PlugIns.
* release.yml — generate .ico (Windows) and .icns (macOS) from the SVGs,
build the QuickLook .appex, and bundle everything.

Windows installer:
- Optional Desktop shortcut feature (default on, deselectable) via a switch to
the WixUI_FeatureTree UI.
- Refresh the shell after install (ie4uinit -show) so .dwg/.dxf icons and
associations appear without a reboot.
- Tidy the Add/Remove Programs entry: ARPNOREPAIR plus contact/update/comments
metadata (Modify stays enabled for the feature tree).
Release workflow:
- Publish SHA256 sidecars for the AppImage, portable .exe, MSI and .dmg.
Linux:
- Ship an AppStream metainfo.xml for software-centre integration.

candle rejects RegistryValue/@Name='' — the DefaultIcon and
shell\open\command rows must write the key's default value by
omitting Name entirely. Empty Name broke the MSI build.

Both the MSI and the portable build were missing Applications\OpenCADStudio.exe\
DefaultIcon, causing a blank generic icon in the "Open with" context-menu list
and the "Choose another app" picker.
- packaging/windows/main.wxs: add Applications\OpenCADStudio.exe\DefaultIcon
(+ FriendlyAppName, shell\open\command, SupportedTypes) to the
DefaultPrograms component for MSI installs (HKLM).
- src/io/file_association.rs: add DefaultIcon to the Applications\
OpenCADStudio.exe block written at runtime for portable builds (HKCU).

Adds a DefaultPrograms component publishing Capabilities and a
RegisteredApplications entry under HKLM. This makes Open CAD Studio
appear in Settings > Default Apps and the shell "Open with" list, so
users can set it as the default handler for .dwg and .dxf files.
Modern Windows guards the actual default behind a per-user UserChoice
hash that an installer cannot forge, so this is the supported path to
becoming the default rather than silently overwriting the association.

Moves the WixUI_Minimal UI and finish-screen launch checkbox out of
main.wxs into a dedicated ui.wxs fragment, referenced from main.wxs via
<UIRef Id='OpenCADStudioUI'>. Keeps the package/feature definition and
the UI concerns in separate files.
Updates the release workflow to compile both .wxs files (candle now
writes per-source .wixobj into a directory) and link both objects.
https://claude.ai/code/session_01DFVSKgViFaxEjZD2KsTdtt
Adds WixUI_Minimal UI to the WiX installer so users see a proper
Welcome → Progress → Finish wizard. The finish screen includes a
pre-ticked "Launch Open CAD Studio" checkbox; clicking Finish with
it checked starts the application immediately after the installer closes.
Also updates the light.exe invocation in release.yml to include
-ext WixUIExtension, which is required to link the WixUI dialogs.
https://claude.ai/code/session_01DFVSKgViFaxEjZD2KsTdtt
A single ProgID with two `<Extension>` children, each carrying its own
`<Verb Id='open'>`, makes WiX emit two rows with the same Registry
primary key and light fails with LGHT0130. Split into one ProgID per
extension (`OpenCADStudio.DWG`, `OpenCADStudio.DXF`); both still invoke
the same exe with the file as `argv[1]`.

Cross-platform prerequisite for OS-level file associations: the boot
task now consumes `std::env::args_os().nth(1)` as a path and dispatches
`Message::OpenRecent` for it. Flag-style args (starting with `-`) are
ignored, and `OpenRecent` already does the file-existence check, so a
bogus path lands as a clean command-line error instead of a panic.
Linux: the AppImage's desktop entry adds `image/vnd.dwg` alongside the
existing `image/vnd.dxf` MIME type and grows a `%f` placeholder in
`Exec=` so the launcher forwards the picked file path. Once the
AppImage is integrated with the system (xdg-mime / AppImageLauncher),
double-clicking a .dwg / .dxf opens it in Open CAD Studio.
Windows: new `packaging/windows/main.wxs` defines an MSI installer —
per-machine install to `Program Files\Open CAD Studio`, Start Menu
shortcut, `MajorUpgrade` so newer MSIs replace older ones, and a
single ProgID `OpenCADStudio.Drawing` that owns both `.dwg` and
`.dxf` and launches the exe with the file as `argv[1]`. The icon is
pulled from the SVG logo, converted to multi-resolution ICO at build
time with the runner's pre-installed ImageMagick. CI now also runs
`candle` / `light` (WiX Toolset 3, pre-installed on `windows-latest`)
and uploads both the bare `.exe` (portable) and `.msi` (installer)
to the release.
macOS Info.plist already declares the DWG / DXF UTIs; combined with
the argv-handling change above, double-clicking a drawing in Finder
will open it in Open CAD Studio without further packaging changes.
