Starred notes are a convenient way of keeping important notes close at hand. Enabling the plugin will create a star icon on the left panel, which brings up a list of starred notes.
To star a file, you have several options. You can do so from a right click in the file explorer, a click on the options menu of an open note, typing in the command palette, or a hotkey that can be set in Use hotkeys.
Starred files and searches can be reordered by dragging them around.
