Ability to start fsearch through multiple databases in different instances with different window titles

[zDEFz]

Is your feature request related to a problem? Please describe.
In KDE, I can setup multiple activities - on different workspaces.
Many of my activities involve to use fsearch, but the database/search scope is a different one.
That means multiple fsearch windows should be able to open, without fsearch preventing it (cause already open)

Describe the solution you'd like
To give fsearch the ability to load a different database and then to use the database name as part of the window title.

Describe alternatives you've considered
