Might be I was not very clear. Geany is one of few editors that monitors file status right during the session. That is great! When a file was changed outside we receive a warning "The file '/....' on the disk is more recent than the current buffer." Reload/Overwrite/Cancel We select Cancel to see changes. Right? But, people can be distracted, and later we can press "Save All", for example. This file will be overwritten without further warning. One day I lost a content in a similar way, and after it I researched what other editors are doing in that case. gedit, emacs, vim, and many other editors warn every time when "the file on the disk is more recent than in current buffer", and not just once.
