For privacy and portability the text editor in Tails Live OS is no frills. Notes are basic text files, persisted to a password protected and encrypted disk partition, with the option to additionally encrypt and password protect individual files. Notes are saved in a standard format and can locked down in an instant simply by pulling the Tails USB from whatever device you happen to be using.
