[ImageJ-devel] error: Unrecognized command: "Versatile Wand"

The minimal-ij1-plugin's main method sets the plugins.dir prior to
launching ImageJ (see footnote [1] below for an explanation why), using
some special code:
https://github.com/imagej/minimal-ij1-plugin/blob/06655b85992b1908d3567f6f177da2c7dad40420/src/main/java/Process_Pixels.java#L176

Your postcards plugin removed that code:
https://github.com/ad1054/Postcards/blob/6cdff5e8d98e6f81ebb01919709b128400de0f1e/src/main/java/A_Postcard.java#L33

Add it back, and things may work better for you.

Regards,
Curtis

[1] For plugins to be recognized by ImageJ1, the "plugins.dir" system
property must point to the folder containing your plugins. And there can
only be one such folder. Or, if plugins.dir is unset, then ImageJ looks in
the "plugins" subfolder of the current working directory by default. The
main method of minimal-ij1-plugin sets plugins.dir for you, for convenience.
