Expected Behavior

There are two sets of refactoring that can be performed on our codebase to make them more efficient and utilize the full potential offered by Qt Framework. See below:

1. There is no need to explicitly call delete on widgets that are allocated on Heap as long as in their constructor we have specified the parent widget for it. Consider this example below:

class Widget: public QObject

Currently, the design decisions and code descriptions are maintained in a file development_notes.txt. Move it to the repository wiki.
