Pinned tabs work when tabs are enabled through the following interactions:

• from the context menu of a tab ("Pin" / "Unpin")
• via keybinding
• via global action from the command palette targeting the active editor

Verify

• tabs can be pinned and unpinned in each editor group
• pinned tabs always appear before unpinned tabs
  • opening a new tab always opens it after the last pinned tab
• pinned tabs remain visible even when many tabs are opened and scrollbars appear
  • non-pinned tabs scroll "under" pinned tabs
  • pinned tabs eventually scroll as normal tabs once you make the size of an editor group small enough (120px is the limit)
  • the active tab is always fully revealed in the presence of pinned tabs
• pinned tabs show with a small fixed size
  • showing only the icon if icons are enabled
  • showing the first letter of the file name otherwise
• pinned tabs can only be closed explicitly (e.g. via CtrlCmd+W) and are exempted from mass close actions (like "Close Others")
  • enabling workbench.editor.limit.enabled will never close a pinned tab when the limit is reached
• pinned tabs work together with any of the tab related settings
  • workbench.editor.tabSizing set to shrink and fit
  • workbench.editor.tabCloseButton set to left, right or off (note that pinned tabs never show any close button)
  • workbench.editor.highlightModifiedTabs enabled to show a dirty indication for dirty pinned tabs
  • workbench.editor.openPositioning set to left, right, first or last does never mix pinned editors with non-pinned
• pinned tabs preserve their state
  • saving an untitled editor that is pinned shows the result as pinned too
  • switching an editor for displaying a resource (markdown preview vs markdown text) should preserve pinned state
  • the command to reopen a closed tab restores a pinned tab at the right index and preserves pinned state
• verify drag and drop
  • moving pinned tabs preserves pinned state if dropped onto other pinned tabs
  • moving pinned tabs onto a non-pinned tab unpins it
  • moving unpinned tabs onto pinned tab pins it
  • this works in the same group and across editor groups or windows
• pin an editor that we do not restore after restart (e.g. a SCM diff editor) and verify that after restart the number of pinned vs unpinned editors is not broken
• disable tabs when you have pinned tabs and ensure that they drop their pinned status (e.g. now mass close commands work on them)

I noticed that the pinned tabs (without file icons enabled) do show the first letter of the file name - but it is always capitalized. I think it would help to distinguish pinned tabs if the first letter of the filename follows the case of the actual file.
