It surely lacks basic important features like sorting through alphabetically, highest to lowest holdings, highest to lowest in profit, vice versa, etc. Also, I really don't like your user interface. It looks so plain and boring in my opinion. Pretty much like a mid 2000s web design. Your interface is responsive though, so that's a plus. I suggest using Bootstrap[1] for your UI/UX.
Thank you very much for your feedback, we will definitely take it into account for the upcoming release, especially the lack of sorting. What other basic important features did you miss?
