More inviting entry point.... provide 1 sample tree in addition to importables

[emyoulation]

We could bundle a tiny sqlite tree database which would be added into the default grampsdb folder during install. Then that tree will naturally appear in the tree list in the Manage Family Trees dialog that already appears.

Here I’ve added a rough version to an old version of Gramps. (It was started with 5.1.5 Portable Apps, then revised in 5.2 on Fedora. The database should only be modified on the Release version or older... so we don't accidentally lock out Release users by editing with developmental versions.)

A proposed Dashboard layout with more content for the user

The compressed file is 12.7kb. A ReadMe.txt was added in case the database becomes separated from the Gramps application. And it uses a media object from IMAGE_DIR constant. It also has a ToDo note.

(So if the install could set the relative meda folder for that tree to the IMAGE_DIR value, then there won’t be the broken link annoyance related to installer OS path differences.)
