In Libreoffice, the background color of application windows
can be set via the menu entries Tools --> Options -->
Application Colors.
Because I do not like the default white, I set the window
background to a light green (#90BB90). This will work for
most application windows except those within
LibreOffice Base can connect to a MariaDB database using one
of three connectors:
JDBC
ODBC
C connector
Setting up a connection using any of the above requires
specifying the name of MariaDB database with which to connect.
However, only the JDBC connector will connect to the specified
database.
