Orion should store bookmarks as files. Each bookmark is a file inside a bookmarks directory.
There should be a "open in file explorer" button to open the directory in system file explorer.
I have trouble managing bookmarks in Firefox because the affordance is so bad.
First, when I want to store a bookmark, I only need to put specific bookmarks in folders, and the rest in "Other bookmarks". The behavior of Firefox (not configurable) is to always use the last folder chosen by default.
Also, managing existing bookmarks is a pain, as the GUI doesn't allow me to use UNIX tools to move bookmarks around.
If possible, I hope Orion will store bookmarks as files so I can manage them with file explorers that have way better afordance.
