Their Response to the 'Original' Bug

[This is the team's response to the above 'original' bug]

The CLI application target audience is for fast and accurate typer. The use of case-sensitive commands was to ensure that the commands to input will be short but clear especially when there are multiple words chained together. Eg, listEverythingAll. In fact, we chose to use camelCase for the commands so that it is easier to use.

## :question: Issue severity Team chose [`severity.Low`] Originally [`severity.Medium`] - [x] I disagree **Reason for disagreement:**  While I acknowledge that this can be identified as a feature flaw, the fact that they did not mention commands being case-sensitive in the user guide makes it a documentation bug too. Following the bug severity labels provided, having case-sensitive commands would fall under medium severity as it does causes occasional inconveniences to users but they can still continue to use the product. Take for example, in order to use the application, the users must be very mindful of the camelCase commands that they have in order for the command to work. This would greatly inconvenient the users as a simple mistake would render the command as unknown. In addition, by enforcing camelCase for their commands, it makes it difficult for users to use their application. The use of camelCase was unnecessary as adds complexity rather than clarity, as well as difficulty rather than ease to use, which was completely opposite of what the team have claimed. To add on, the following is a snippet of how unnecessarily complicated commands could be identified as a bug.
