How do I open separate tabs/windows for all buffers in Vim?

To split all buffers use :sba or :vert sba

Vim command :sba has also a shortcut: :ba.

:[N]ba[ll] [N] :[N]sba[ll] [N] Rearrange the screen to open one window for each buffer in the buffer list.

To back again to single tag, use: :on (:only).

:on[ly][!] Make the current window the only one on the screen. All other windows are closed.

To quit, use: :qa

How to convert buffers to windows/tabs:

• buffers > horizontal windows: :ba (buffer all)
• buffers > vertical windows: :vert ba (vertical buffer all)
• buffers > tabs: :tab ba (tab buffer all)

How to convert window/tabs to buffers:

• windows > buffers: :on, :only (current window only)
• tabs > buffers: :tabo, :tabonly (current tab only)

If you want to convert all windows to tabs, first convert windows to buffers, then buffers to tabs:

:on | tab ba
