New window button when creating new project

[PastaLaPate]

Is your feature request related to a problem?

When I want to slice 2 models in different windows i need to re-search cura in search bar and re open the whole software which is very slow.

Describe the solution you'd like

On the top menu bar File -> New project when something is in the project the dialog with buttons Yes or No (Are you sure you want to start a new projects and clear build plate etc) It would be good if another button like New Window created a new window for the new project instead of creating it in the current window.

Describe alternatives you've considered

Re opening a whole new window -> Very slow because of loading UI, plugins etc

Affected users and/or printers

Everybody which needs to have multiple windows at the same time.
