[Tomasz Wlostowski <tomasz.wlostowski@xxxxxxx>]

Hi,

One of the biggest annoyances of Kicad (to me) was the PCB forward
annotation process. The attached patch set attempts to improve this by
adding an "Update PCB From schematics" option in eeschema when Kicad is
open in Project Manager mode. The way it works is:
- press F9 (or select Tools->Update PCB From Schematics) in eeschema
- a window with changes to be applied to PCB will appear
- you can check for errors/warnings/review what is going to be changed
- click "Perform PCB update" or press Enter to proceed (or cancel).
- netlist updates can be undone (Ctrl-Z restores PCB state after wrong
netlist load).

Best,
Tom

PS. Henner, thanks for the inspiration by sending your UX improving
patches ;)

+ *
+ * The changes are made to the board are as follows they are not disabled in the status
+ * settings in the #NETLIST:
+ * - If a new component is found in the #NETLIST and not in the #BOARD, it is added
+ *   to the #BOARD.
+ * - If a the component in the #NETLIST is already on the #BOARD, then one or more of the
+ *   following actions can occur:
+ *   + If the footprint name in the #NETLIST does not match the footprint name on the
+ *     #BOARD, the footprint on the #BOARD is replaced with the footprint specified in
+ *     the #NETLIST and the proper parameters are copied from the existing footprint.
+ *   + If the reference designator in the #NETLIST does not match the reference designator
+ *     on the #BOARD, the reference designator is updated from the #NETLIST.
+ *   + If the value field in the #NETLIST does not match the value field on the #BOARD,
+ *     the value field is updated from the #NETLIST.
+ *   + If the time stamp in the #NETLIST does not match the time stamp  on the #BOARD,
+ *     the time stamp is updated from the #NETLIST.
+ * - After each footprint is added or update as described above, each footprint pad net
+ *   name is compared and updated to the value defined in the #NETLIST.
+ * - After all of the footprints have been added, updated, and net names properly set,
+ *   any extra unlock footprints are removed from the #BOARD.
