It would be useful to filter the price history for selected launchers or stores.
If you end up being tied into a particular launcher (Steam, Epic, etc) for the base game, then any DLC you want needs to be purchased in the same launcher as the base game. It would therefore be helpful to be able to only see the price history for a particular launcher (or store if it's easier) to see if the current price/sale is a good deal.
Take for example SnowRunner, I purchased it on Epic. At the time of release it was an exclusive to Epic. Since then it has released on Steam. I'm interested in purchasing the Year 2 Pass, but want to only see the price history for the Epic launcher. Steam has a large key-shop support, and subsequently everything is considerably cheaper for Steam, thereby dominating the top 3 lowest price spots of the price history. I now can't tell if the current Epic sale is good or not.
