KiCad Library Manager

1.2.0

• Project Doctor: reconcile a downloaded KiCad project against your own library. Click Project Doctor, pick a project (auto-discovered from Documents/Downloads/KiCad, or by path), and the same table lists every symbol & footprint the project uses — flagging what isn't in your library in red, and scoring project health with a segmented bar (green = your own · amber = stock symbol · red = missing). A stock footprint counts as healthy; a stock symbol is flagged (use your own).
• Footprint recommendations use geometric (shape) matching, not names: pad count, pitch, pad size and body box are fingerprinted from the project's placed footprint and matched against your library and the full KiCad default library (~15k footprints, fingerprinted on the desktop in ~2s and cached). So a custom 2920L030DR finds Fuse:Fuse_2920_7451Metric and a C_0402_1005Metric finds Capacitor_SMD:C_0402_1005Metric — by shape, with zero name overlap. The dropdown tags each match with its shape (e.g. 2 pads · 0.96mm pitch); falls back to name matching when a footprint isn't placed on the board.
• Every symbol/footprint is an editable, autocompleting bar — type or pick one of your own library parts to remap onto it. If the name exists in your library it's a change (repoints the project to your part); if it doesn't it's a rename (relabels it inside the project). Edits only ever touch the project, never your libraries, and are tracked like any pending change.
• Sync rewrites the downloaded project's .kicad_sch/.kicad_pcb to apply the remaps (lib_id + footprint references, with the symbol's lib_symbols cache injected so KiCad resolves it), backing up every file to .klm.bak first. New endpoints: POST /api/projects, /api/project-scan, /api/project-edit, /api/project-close.
• Fixed: klm app now opens the webview through $VSCODE_PROXY_URI so it's reachable from the Hydrogen front-end (was a raw 127.0.0.1 URL that couldn't connect).

1.1.1

• Sync now prunes dead lib-table entries (paths that no longer exist) from sym-lib-table / fp-lib-table, so KiCad stops erroring on launch after a library is deleted. Backs up each table to .klm.bak. Also exposed as POST /api/prune-tables.

1.1.0

• Footprint previews: pads render above silkscreen with pad numbers on top
• 3D model preview (STEP→GLB) for footprints and a dedicated 3D Models view
• Live JLCPCB stock + price on hover over an LCSC part number
• Pending changes: deletes flag red, adds green, edits outline the changed field orange; header chip shows new / deleted / changed counts
• Sync is a repeatable one-shot (resets after) with per-library sync; deleted libraries get unregistered from the lib-tables
• Tabs renamed to Symbols / Footprints / 3D Models
