This is interesting to say the least. I tried out Vortex on my last major Stardew Valley playthrough and I found it a bit clunky. I got it to work, but I feel like it had a learning curve to its own vocabulary and how it organized everything. Then when I found a few of the mods recommended skipping Vortex and just doing a direct download, I keyed in to a much simpler workflow I could wrap my head around with updating the mods.
Interested to see what the new app might look like in time. If they can take lessons learned from Vortex and apply them forward, that’s great.
