I use a filter to see if I have wedding certificate and it would be usefull to be able to filter by city for my research.
I use this method for birth and death certificate and it works perfectly.
Someone else asked about that (but I cannot find the thread) and @kku has created a view with this and another enhancement. FamilyView-2
This is a manual install so you first need to know where Gramps stores addons on your computer. It will be in your user directory/gramps60/plugins folder.
The easiest way to get the new view is to download all of kku’s addons in a zip file (the green Code button) to your computer, then pluck the FamilyView-2 folder from the zip folder into your plugins folder. There are other addons kku has written which you may wish to explore.
When you restart Gramps, a second view will be added to the Families’s navigation category.
