SCM used to allocate one workbench view per repository; it now is able to show all data in a single view. You're supposed to run a more or less thorough SCM smoke test, but here are some pointers:

• The single repository view should work pretty much as before expect for the hopefully insignificant fact that the input box now scrolls with the tree. 🤫
• As for the multiple repository view:
  • All repositories should be represented in the tree, including their respective status bar actions as well as contextual actions
  • Clicking around the view should influence which repository appears in the status bar. The same goes for switching the active file in the editor
  • It should still be possible to switch between rendering the contents as a tree or list
• The input box is a monaco editor: it should still automatically grow with its content (up to a certain max) as well as render widgets (suggest widget) and validation (have a commit message comprised of only whitespace to see a warning)
• The welcome view should work as before, eg open a new window and see if welcome view content shows up
• Move the view around, into another viewlet and panel
