Here is a challenging one for someone.
I have two tables in QGIS.
Holes (parent) - Which contains the borehole locations. Strata (child) - which has many rows that contain the strata for each borehole
Although i can see this join in QGIS it would be really useful to be able to export a KML that has each point and a popup that has a table of the strata at each point...
