Automatically saving and restoring terminals with tabs and separate histories, per workspace.

I have found nothing yet that does this, or even just one of those things. It would be the killer feature of a new terminal emulator - and I see there are lots of them being developed, but none of them have this! And I can guess why: It's because of the maintenance work required to have this feature, and also trying to be multi-platform, multi-desktop and also the work required just to have a working terminal to begin with.

Once upon a time someone here was explaining how to set bash to use the first history file in the ancestor folder of the current working directory. I do not remember how, but it sound similar to what you are asking.
