Saving takes some time when the file is big. I prefer a fast closing
IDE.
Maybe some option can be added.

Why that? Simply start a second instance for testing.

Yes, the empty database on first use is currently the show stopper.
It would be great, if it somehow (TM) knows at least the FPC and Lazarus
sources after install.

The IDE parses the sources on demand when information is needed. It is
not available per se.
Since parsing a project can take some seconds even on fast machines,
this is not done automatically.
Maybe the dictionary can start parsing the project on idle when it is
shown to update its database.
