+1 for this feature request. At work (on ms-windows) I use Notepadd++ which does this, and it is very useful. At home (Linux) I use either Geany or Sublime Text (which has this feature too, but is not open source). This feature really does give you a kind of peace of mind: 1. The editor do not ask you anymore what you want to do with unsaved files when you close it (either voluntarily or during a crash). 2. When working on a file saved on disk, if modified in the editor, then on reopening the modified and unsaved version is opened for the user. 3. When working on files not yet saved (an "untitled" one), they are also reopened with their content. Keeping info in an unsaved buffer might be seen as dumb. But it is very useful! I do it often for not important data, which I could build again if needed. Think for example a temporary text conversion between an export and a work in excel or calc. Or a copy paste to remove the formatting between apps. I'd like to be able to code this, unfortunately I don't have these skills, let's hope someone can do it :)
