 1. **Make the User Interface (UI) adapt to different window sizes:** Currently, the UI can only work at specific sizes, the user may need to adjust the window size such that all the components in the UI are visible during use, or when the application initially boots up. We plan to enhance the UI such that it is able to adapt to different window sizes and not have issues like components not being visible, or having white spaces when the window gets stretched too much.
 2. **Standardizing Error Messages Related to Index:** Some error messages related to commands that utilizes Indexes (e.g `delete`, `note`) do not have standardized error messages. Users may sometimes see "The person index provided is invalid", or different error messages referring to the same error. We plan to standardize such messages so that they do not cause confusions for user and make the experience when using the application smoother.
 3. **Allowing Contacts to Have the Same Name:** The application does not support people having the same name, even if they are two completely different person who just happens to have the same name. We plan to update this in the future such that this will become possible as it makes sense in the real world for two or more people to have the same name.
+4. **Fix Feature Flaws of Profile Picture:** The profile picture feature may only work if users follows a very specific set of instructions to generate the `.json` file that stores the applicant information. This is due to buggy implementation of said feature, which did not follow the Command design pattern due to an oversight, which is thinking that the feature is a UI feature, so it does not need to follow the design pattern. We plan to fix this such that the feature will be able to work without strict constraints.
+5. **UI Text Truncation Issues:** When some of the applicant's information is too long, it gets truncated and does not display properly. We plan to fix this in the future by creating a more robust UI that can adapt to applicant information with long length by displaying such information in a viewable and proper manner.

+### Updating applicant profile picture (Part of Planned Enhancement)
+Each applicant has a `Update Picture` button, which enables the user to add a profile picture for a particular applicant.

+**Note:** Due to buggy implementation of this feature, a very specific set of steps needs to be performed in order for this feature to work.
+1. Before using this feature, use the `list` command at least once. This allows the `.json` file that stores the applicant information to be generated.
+2. Press the `Update Picture` button and select an image (only image file types are supported, using other file types may corrupt the application).
+3. After choosing an image, a popup should appear that explains to you that the application needs to be restarted for the changes to be reflected.
+4. Restart the application, and you should be able to see the profile picture being updated.
+5. In rare occasions, the feature may not work due to operating system complications.
