It would be amazing to be able to import CSVs as effortlessly as you can in Miro.
You can literally just copy a column from a spreadsheet, paste it in, and each line gets turned into a sticky!
Edit: A really strong use case for me right now is when I am done conducting surveys, I love being able to download the results and just drag them into Miro for definition exercises (affinity mapping, empathy mapping, etc.).
