Hello,
when working deep down a folder hierarchy, up to 3.6 opening a new tab will still keep you in the same folder.

This is extremely useful, for example, if when working on a project you use one tab to edit files, another attached to the logs, another with a shell for miscellaneous commands. A pretty common use case, I think.

I personally used this feature a lot, but I understand that technically a new tab could be used for something completely different. Sadly it is a matter of typing "cd" to get to the home dir, instead of finding one's way back to the previously used folder. 
I think that the nautilus "open terminal" feature existence testifies to the difficulty for users of navigating the filesystem in the shell.

Some possible ideas:

1. revert to the behaviour as in gnome 3.6. I do not know if this is just a regression or it was intentional.
2. add a new menu item: "open a new tab in this directory"
3. add an option to choose which behaviour is preferred
4. set the OLDPWD variable in the new terminal to the pwd of the origin tab, this way running a "cd -" will take you back. Simple and explicit.

I think that no one would be upset by 3. or 4.

Thank you.
