Graphite supports annotations, but only when files (documents, tables, mind maps) with proprietary formats of Graphite enter file editing mode. This function is a bit lame. I used graphite for a long time before, but because of this limitation, the work efficiency has decreased, so I don't mention it. The recently used Fang Yun is much more convenient than graphite. It supports file (folder) comments and voice comments, which can be @ all employees or @ someone, and also supports message reminders, so I don't have to use the network disk and social software to cut back and forth, which improves my work efficiency.
