When connecting to my WiFi this was a huge blessing - because even the toy WiFi for the Switch has a decent password, and again when uploading SMM2 levels. It's a little bit painful to watch really great creators like Barb or PangeaPanga uses a pad to write names & descriptions.
"It can't be bargained with. It can't be reasoned with", but the Youtube video has to cut there because Barb will proceed to take about a minute to painstakingly enter the text. It's not a big deal, but it jumps out because that's the only part I find easier. (I suck at Mario, but it's fun anyway).
