Add option to accept changes while preserving Diff view for multi-file comparison in IDE

When editing and reviewing multiple files in a pull request or commit, it would be helpful to have the ability to accept or stage a change while still keeping the previous diff visible. This would allow developers to:
• Compare the updated code with the original even after accepting a change
• Maintain a continuous review flow without losing visual context
• Avoid reloading or navigating back to the diff view manually

💡 Suggested Feature Behavior:
• After clicking “Accept change” or staging a hunk, the Diff view remains visible
• A toggle or setting to keep diffs open after edits
• Useful especially during complex refactors or when reviewing multiple files in a PR

This feature would greatly improve productivity and make it easier to keep track of what has been changed, especially in large pull requests.
