If you’re on Gnome, you can use Frog for step 1 then Dialect for step 2.

I use Rnote to write freely on a big whiteboard and Xournal++ for taking notes over PDFs of lectures.

The Perks of Being a Wallflower is one of my favorite movies. Although he’s not without friends the entire movie, I think you might still appreciate it.

Although I haven’t seen it yet, Lost In Translation is near the top of my watchlist. It might be up your alley.
