Some thoughts about PADDs
I had a thought that began with this scene from Lower Decks.
T'Lyn just...tosses it out the window, the modern day equivalent would be to chuck my phone out of a car to delete a google doc.
Its obvious that PADD were designed 24th century visual metaphor for presenting hard copy information between characters, like envelopes or reports, or ancient scrolls in period dramas.
Because they were fictional, the user processes hadn't yet been developed (TNG premiered in 1987, iPhone first release in 2007, iPad in 2010). Nobody knew to forward files from one device to another; if you notice, in TNG/DS9/VOY often someone, like Riker or Geordi, will physically hand their PADD to Picard so he can read their report.
This scene in DS9 is the equivalent of they're the same picture meme
So Trek carried on the metaphor further by having multiple PADDs on someone's desk to show accumulated paperwork:
Then there's Jean-Luc's challenges with organizing and prioritizing in Insurrection.
My personal head canon is that between now and the 24th century, it was found that having multiple tabs open on a device was somehow harmful to one's mental health.
