I opend a new file, input some content e.g.
then I carelessly close atom,
without any reminder, it is just closed directly. And my two hour’s work had gone, and now I’m so depressed, frustrated, angry.
Why not have a popup to remind you there are some files are not saved just like close the tab. When close a tab and you do not save it, it will have a popup with the info：
‘untitled’ has changes, do you want to save them?
Your changes will be lost if you close this item without saving.
