One of the coolest features in my QGIS workflow is the ability to copy features (select and copy) and then paste the results into, say, Excel or Openoffice - you get your attributes table plus a WKT column that describes the geometry:
wkt_geom id name POINT(250000 9012000) 1 Home
(You can then parse this directly in Excel using something like
=MID(A2, 7, 6) to get the X value of the point).
What would be even better is to be able to edit that table in the external app, copy it again, and paste it back into QGIS (with the relevant layer in edit mode). However, I've tried that without success - QGIS remembers its set of copied features from the previous operation, ignoring the system clipboard (which I've confirmed has the right table stored).
Any clever ways to make this work?
