I often like to the see the price history of the cards in my collection, especially when one dramitically changes.
I use the site https://www.mtgstocks.com/ to see the history of the card and would like to be able to click on a card in my inventory and then click on the link to MTGStocks, similar to how it is done for TCG Player prices.
I am not tied specifically to MTGStocks but that is the only service that I am aware of that provides this information in an easily digestible way. If there are others that are better, that would work for me as well.
