Describe the feature

I would love to have the ability to switch the tab layout to vertical.

just like JetBrains do. this feature request is somewhat related to #5240, yet it's not a request for a separate pane, only the ability to switch tab layout.

If applicable, add mockups / screenshots to help present your vision of the feature

[syntastical]

Yeah, probably seems trivial to most, but vertical tabs has become a crucial part of my IDE needs.

I'm just playing around with the source code to get more familiar with it.
I'm not sure if the zed devs will accept the changes or not, or how generally the process (I've read the CONTRIBUTING file) works? It's not a tiny change, it's also not a big one!

So far, it's like the screenshot below, but it's not resizable, and it's just top or right (and none, to remove one config? and I will try to add left and bottom also).
It's not a pane, it's exactly the same tab_bar we have on top.

Ref: #6667 (comment) (and a bit #5240)

PS: the code is not close to ready to be a PR.

hey @omid could you somehow share your WIP changes? I would like to contribute to the development of this feature too, but I don't want to start from the scratch

[omid]

@m-czyz sure. But be aware that it's just a PoC.
For example, I completely commented out the top bar, instead of handling it by conditions.
I made a PR here for this branch.

PS: We can remove tab_bar.show config also. And add a None to TabBarPosition enum.
