notepad/dictation/search? pretty sure the issue is you will NOT make mention of where you placed stuff. Often we misplace stuff because it's tangential to the task, and we're in a hurry to transition back to the main focus.
Tangential exactly (which is why something like a spreadsheet would never work.) I've tried using notes but then I often forget exactly which note I used or how I had planned to access it later. But I imagine myself being able to quickly tell the app "I'm a stashing X at Y" without a lot of cost.
for those with an affinity for ios. seems like notes and siri are actually a viable solution. No idea how many notes ios can hold, or how search performance goes?
