Calligra Sheets is a spreadsheet application which is developed as part of the Calligra Suite(KDE). The task here is to test various features present in the application and provide suggestions to fix it/improve it. If interested, you can help with code fixes(Optional) but the requirement is that the student tests at least 5 different features in the sheets application and provide a document containing suggestions for improvement(if any)/ fixes(need not be code).

As we are on the verge of making Calligra Sheets a very mature application, this task would be useful in a way. This task would also be fun for the student as he can learn interesting stuff about spreadsheet application & also learn testing.
