Improvements to the Functions Deck & Functions Wizard in LibreOffice Calc

LibreOffice Calc has a nice functions deck on the sidebar allowing to pick one of the many functions, and this functions panel has some room for improvements. These enhancements can be also applied to the functions wizard. The project aims to improve this deck to enhance usability and functionality. This includes improving search techniques, enhancing the user interface, and incorporating other features like having a list of favorite functions and a help button to go to functions documentation.
