I like the Movements feature for each of my holdings. It separates out all the trades and dividends of each item. I was getting a bit upset because my 'bulletproof' Westpac shares are down 6% since I last bought them. But looking at all its movements and dividends, I can quickly see that overall I'm up 10% with Westpac.
I also keep track of what my shares are doing on Simply Wall St with its nice coloured balloons.
