Not sure I understand the issue. On Ubuntu every time I open pgAdmin4, it opens up a new tab on the browser. If it's not in a separate browser window, just drag the tab out and Firefox at least will open a new browser window.
I have 3 pgA4 windows open right now.
Maybe I am missing the point, wouldn't be the first time...
This is probably my 10th attempt to move from pgadminIII to pgadmin4. At least the performance has significantly improved over time and seems now acceptable.
The biggest drawback is however that all elements are locked up in one browser window – I cannot find any option to detach a query windows and put it on a different monitor.
95% of my time I use pgadminIII just to type select and update statements and review the output rows.
I know that I can do this in psql but it’s not handy with many columns.
For that reason we currently stay with pgadminIII (and this is for us also one of several reasons to delay any move from 9.6 to a more recent version).
