How many times happens that a very annoying bug makes a normal workflow nearly impossible or, worse, you cannot work on the project anymore?
With a bug we discovered some times ago, you cannot select the parent geometry from the child form geometry, both layers are linked with a 1:N relation:
Immagine a project in which you have 20.000 child lines and 2.500 parent lines. You have to manually associate the child to a parent because there are not fixed spatial criteria: you have to choose the parent layer manually on the map.
How would you do if the bug is there? Well you have to open 2 attributes table click on the child feature, select the parent feature from the other opened attribute table and manually copy/paste the code you are looking for.
AKA: hours of work where the chances of making big mistakes are massive.
What does it mean? We are really interested in the development of QGIS: we are not just users, we report bugs and work together with the QGIS team. Every day.
