Support Vim tabs

[ap]

There’s no reason this couldn’t incorporate Vim tabs by just showing a | 1 | 2 | 3 |-style display at either end of the tabline. Clickable ’n’ all. They would not have names, just numbers, but that’s OK, Vim fakes that part too, and it’ll help keep the display compact since the space is needed for buffer labels.

I'd love to see this! As much as ‘tab’-viewports see very little use in Vim … when you want them, you really want them.
