User Interface & Usability

• Sourcetree uses a multi-pane layout:
  • Left sidebar: repository tree, branches, tags.
  • Top pane: commit history graph.
  • Bottom pane: file diffs and staging.
  • Pros: Power users can access every Git feature without the CLI.
  • Cons: Can feel overwhelming; panels can be crowded.
• GitHub Desktop opts for simplicity:
  • Two-column layout: changes on left, history on right.
  • One-click actions: clone, fetch, pull, push.
  • Pros: Intuitive for new Git users.
  • Cons: Power-user features require falling back to the command line.
