"Open default Database on startup"

Why do I have to always open manually my DB when I open DT Pro? Especially that we can only have one file opened at a time…

With your main database open, press File > Database Properties. On the Database Properties panel, check Default. Then this database will automatically open each time DT Pro is launched.

It’s highly recommended that you make this “default” setting for one database, even if you are using several databases.

like all OmniGroup apps.
