Time is relative. 😃
Also - we've made other improvements to HL in the meantime - including keyshop prices in HL, giving you 2nd best, 3rd best, 3 months low, 12 months low.
Our to-do backlog is huge and we prioritise tasks that have most impact on customer experience. When the time comes, we will add price history in the form of table - it's definitely in the backlog.
