Hi Denis, when I open a Pharo window (like Playground) and select "Create window group" I can drag and drop other windows onto it. So one can group several windows into one, each one shown with an own tab.
This works for most of the Pharo windows (Playground, Iceberg, ...) in latest Pharo 7 - but not for the Calypso browser. I can drag a system browser into the window group - but when I drag it out again it is just a gray window and the content is not usable anymore. I guess this is a bug in Calypso - so I opened https://github.com/pharo-ide/Calypso/issues/287 Thx T.
