Hello Siprex3D,

the shp import plugin is incomplete, at least multipoint shapes are not haldled.

If you want to collaborate might complete the plugin.

Another GIs related feature are add support for DGN files. You can start using
the skeleton of importshp plugin and libdgn from ogr:
http://www.gdal.org/ogr/drv_dgn.html.

To learn about LC plugin creation you can read (outdated):

and read the fully documented file:
