Similar to https://atom.io/packages/bookmarks but bookmarks remain after you close a text editor, and even after closing a project.
Bookmarks are ordered by time of creation.
ctrl-alt-b: Toggle bookmark
ctrl-alt-m: View all bookmarks in current project
ctrl-alt-shift-m: Clear all bookmarks in current project
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
