(I see you've edited your comment meanwhile but I'll leave my comment here for reference)
I've seen some of these but I don't think any of them actually follow the tabbed interface paradigm:
* visible tab bar, preferably at the top and preferably style-able so that it doesn't look like it's out of Windows 3.11
* dynamic tab names based on file contents (in case of multiple buffers, show the name of the currently focused buffer), so that there's no need for manual tab name management
* tab navigation through shortcuts (open tab, close tab, move tab left/right, etc.)
Sorry for edit. I found and installed evil-tabs after replying and it's actually quite good.
It meets all the points you raised, and I agree with them - I prefer evil-tabs for that reason. Although I must that admit that evil-tabs only implements only crucial subset of all vim tabs features mentioned in http://vim.wikia.com/wiki/Using_tab_pages .
