Upgrade to 15.04: What happened to my gnome-terminal tabs?
Evidently, part of the upgrade to Ubuntu 15.04 involves an upgrade to gnome-terminal that removes the old feature that allows new terminal windows to be opened as a tab, instead of a new window.
If I had known this before the upgrade, I literally wouldn't have upgraded. Full stop. I manage many servers, and having an SSH client that allows new sessions in a tab is essential. Opening new windows for 15 servers is completely unmanageable.
In this screenshot, you can see the "open sessions" menu option. There used to also be an "open tab" menu option, with the complete list of sessions I have saved. It's gone now.
Solution 1:
If you want to know how to fix this problem, the new version has the option to open all new terminals in a tab. Go to Edit -> Preferences and then change "Open new terminals in: Window" to "Tab".
Solution 2:
Just downgrade to good old 3.6.2 like me did.
