Tab open and close should telescope, not travel

[mnemnion]

I know opening two discussions in one day is a lot, I won't make a habit of it.

This is opinionated, just getting that out of the way. It's easiest to illustrate with screenshots, the fortunes are as fortune found them, not additional commentary or anything like that.

So with two tabs open, I'm on tab one:

Then I open a new tab with ⌘-T:

When I close with ⌘-W:

I'm in tab two. I would uniformly prefer to be in tab one. I don't even think it should be configurable, it should just do that, not this.

Thus: open five new tabs, close them all, back at where you started. It just makes sense to me that closing a tab has the reverse effect of opening it, and it would be weird if tabs had some memory or hysteresis such that they always jumped back to the tab one happened to be inhabiting when it was loaded (should they be rearranged or what have you).

So, simply this: tabs open to the right, when closed, the tab to the left opens, if there is one.

I look forward to discovering if there are those of you who feel just as strongly that it should be as it is right now! If that proves to be the case, then I take it back, it should be configurable. If I'm the only weirdo who wants it this way, well, I'll deal.

I'm not even sure if we can even control this since on both macOS and GTK we use the native tab widgets and views to implement our tabs. If the system allows us to configure it then we can by all means address that, but I don't think it makes sense to go out of our way otherwise.

On macOS we can definitely control this.

I think the idea that opening and closing new tabs should revert to the same prior state is totally reasonable, as long as its generally possible and doesn't feel weird in the context of the OS. I think on macOS and GTK this would feel totally normal to me.
