I use Text Editor to draft emails and other messages.

Not files that I want to save, just drafts.

Problem: When my computer crashes (happens often recently), I loose the drafts.

Is there a text editor that backs up unsaved files somewhere? (preferably in a single place)

I tried Text Editor (Gedit), and Leafpad.

Note: I don't want ~example files to be created everywhere, because they are a mess in the terminal, and can be dangerous when sharing USB sticks. So unfortunately I can't use GEdit's backup feature.
