So I'm in the middle of doing a game where I'm trying out a bunch of mods. Is there a mod that gives me more options for tracking where my profits are coming from and how much I've made this day/week/season/year per item?
Unfortunately not, a lot of distributed factors are involved in how money is measured in stardew, and SMAPI does not enable us to access all of those factors, so while a generic "+x" or "-x" profit per day graph could be made reasonably easy, further detail is difficult, and full detail pretty much impossible.
Iceburg's Shipment Tracker is still online. It works in SMAPI 1.2 and up. The profit-breakdown charts are only displayed via Iceburg's website, however, not in-game. (Note that the spreadsheet file you need to upload is now located at "/[YOURINSTALLLOCATION]\StardewValley\Mods\Shipment Tracker", not in "%AppData%\Roaming\StardewValley\Mods\Shipment Tracker")
