SUPPORT! A column preview style is absolutely ESSENTIAL. I've generally nice experiences with Goodnotes. But the documents is also general unorganised. When have multiple documents opened, listed them on top of the window makes it hard to manage the window size. One has to keep it as big as possible that it dominates a large proportion of my MacBook display. Also the current style has a flaw displaying when it comes to a long document name (possibly academic paper with a full, long citation).

My suggestion is to give us users a choice to choose between the original, current view style and one list and icon view with multiple columns (folder hierarchy) possibilities. It would give us a more efficient way to browse documents and sort out between folders. It also helps in displaying documents with long names with a more subtle mean showing more preview while displaying the whole name.
PLEASE ADD this feature.

Column view is NEEDED! I like the features of Goodnotes, but it feels unorganized in general. List View and icon view are great if you're only dealing with Photos, but most of the time we are dealing with Files, and files need to be moved, edited, duplicated and opened and closed on the fly.

I love GoodNotes and am, overall, very happy with it. I have a lot of documents stored in GoodNotes and would love a column view as well. Column view is the fastest, most efficient way to browse a folder hierarchy. Please please please add it. Thank you!
