I love having 100 save slots for my parties, but I don't love scrolling through the list to find the one I need. What if when saving a party while in an adventure, you had a checkbox labeled "Default Party for Module". Then the next time you enter that module, you'll see a button labeled "Load Default Party" and with one click you can retrieve your perfectly optimized party for that adventure. This would be really convenient for Loot Fairy hunting. In MP, you could have a default party for each ranked map set.
Good idea! Even better would be to load the default party for each adventure or MP map set automatically as governed by a new option "Always load default party" or equivalent.
