Describe the new feature

Per #2306, we use DB Browser to introduce students to SQL in classes. (Thank you for a wonderful teaching tool!) By default, on macOS, at least, quite a few panels are open by default, none of which are strictly necessary to start creating tables or exploring existing tables:

And I fear they tend to make the tool seem more complex at first glance than it need be, at least for less experienced users (students, in our case). When teaching with DB Browser, for instance, I close all of those additional panels so that students can focus on core features like Database Structure, Browse Data, and Execute SQL:

As via these settings:

While DB Browser's audience is surely broader than ours, might it be compelling to disable some/all of those extra panels by default for new installations, so as to onboard new users a bit more simply? I'm sure a tradeoff might be that some users might not discover those more powerful features, so we do realize our use case is narrower!
