Dear all.
The following will certainly not cause much discussion, but I still wanted to get rid of it briefly. 
I’ve been using GRAMPS for maybe 2 years now. Only under Windows, because I had no other operating system at home. Many attempts to switch from Windows to Linux failed in earlier years due to Linux’ poor hardware support. For various reasons, I have now installed Linux Mint on the laptop on which I always use GRAMPS. And I can tell you, GRAMPS is a rabbit now. A running rabbit that is so fast that it almost scares me.
Starting GRAMPS, loading the family tree, navigating in the graph, filtering, editing, exporting … everything is faster. Much faster. This experience alone will prevent me from using GRAMPS under Windows again.
