Describe the request

Expected behavior when closing the last sketch (window):

• Arduino IDE does not quit.
• The Arduino IDE icon stays on the dock.
• Clicking on the icon opens a new temp sketch. Every time the user clicks on the icon on the dock after closing the last window, the temp sketch number increases: for example sketch_sept15a, sketch_sept15b, etc.
• The Arduino IDE status bar remains active and usable. For instance, macOS users can open a sketch from the sketchbook, a recent one, an example, etc.
• macOS users can quit the application from by selecting Arduino IDE > Quit Arduino IDE from the macOS menu bar (or with ⌘+Q).

🙂 This will enable opening sketches in Arduino IDE even when no sketches are currently open.

Describe the current behavior

Arduino IDE application closes when the last window is closed.

🙁 This is non-standard behavior on macOS.

Additional context

Unlike macOS. It is standard for applications to close when no window is open on Linux and Windows. So the current behavior of Arduino IDE on those operating systems is correct.
