A User of Lumin PDF
January 24, 2020
Pros: My high school debate team uses Lumin to prepare for tournaments from home. The design tools make it really simple for them to organize the arguments, pull out their arguments and evidence visually, and best of all -- as any high school teacher can appreciate -- everyone can edit in Lumin so there are no more arguments between students about one making all the decisions (or at least, fewer!).
Cons: If you click on the icons, nothing happens; you have to click a bit to the right, instead. It was a bit annoying at first, but not a big issue once you get used to it.
