Hi, everyone. This was discussed here, here and here; and the current solution is:
$ gsettings set org.gnome.desktop.wm.preferences resize-with-right-button true
But I’d like to request the addition of this option to the Multitasking section in the Settings app.
I’m also running elementary OS, and this is the default behavior there, and I really like it.
Other than this little issue, I’m very happy with GNOME. The defaults are well designed. Thanks!
