- Added a new div container in profile-edit.php for better layout structure.
- Removed the back button from candidate-profile.php to streamline navigation.
- Updated proposed-candidates.php to open candidate links in a new tab for improved user experience.
- Modified registration forms to make the profile visibility checkbox optional, enhancing user flexibility.
