[UI] Divider lines hinder usage

[nus-pe-bot]

The current UI of the product prints two divider lines for each line of output (in most cases). See the image below for reference:

This is not a good design, because:

• After some usage, the UI becomes very cluttered and hard to read. More lines are being allocated to dividers than to content.
• Some commands (e.g. view-budget) print more than one line.
• It becomes difficult to distinguish between user input and program output.
• Printing two lines is enough (one at the beginning and one at the end of the output), as opposed to two line for each category.

Team's Response

This is a design-related issue, as the use of divider lines is intentional and does not affect the functionality or correctness of the program. The output is accurate and readable, and the issue lies in the aesthetic or usability design of the dividers. The impact of this flaw is purely cosmetic and does not interfere with the program's normal operations. It does not affect functionality because the output is correct, and all commands work as expected. While the dividers may appear excessive, they do not prevent users from understanding or using the output. At most, it makes the interface slightly more cluttered. Some users may not find this problematic, as dividers help visually segment output, especially in command-line interfaces. Given that this is a minor issue that does not inconvenience users significantly or affect normal operations, it qualifies as a very low severity feature flaw.
