Hello,
I have a feature request, but in year 10/2019 still not available in PLSQL Developer v.13.0.6

Most of professional developers have multiple monitors on the working desk. I have 3 monitors.

I'm working in PLSQL developer on main monitor and I have a SQL window opened. I have a SQL prepared or resulted a data from query. I need to _MOVE_ this window to secondary monitor to start a new SQL window/procedure/package,.... . I also need first SQL windows still available for my eyes, because I'm going to compare results/compare ideas or compare/control/check some logic from first SQL window.

Current workaround is not very comfortable:
1. Use different application: Copy important code to sublime or copy result data to excel
2. Open secondary plsql

Any plans to enable this?

We currently have no plans for this, but I have added this to the list of enhancement requests.

In the upcoming version 14.0 you can compare result sets directly in a single SQL Window:

Ohhh....that is very nice! Great job!

Wow ... this would be awesome @Marco.
Do we have an ETA on version 14?

We'll have a public beta version this year or early next year.
