Moronic Developer Tool Writers
You know your little programs are going to crash. Why is it that fucking vi has had a autosave feature for what must be a century by now, and highly volatile programs like Quartz Composer dont ? I regularly lose work in Quartz Composer, because I am experimenting with something and that biotope-for-programming-errors bombs away. Autosaving to /tmp or whereever should be like the first feature to implement, when you release an editor of some sorts.
I rag on Xcode for the same problem. Now Xcode has become pretty stable with 2.1, but that doesn't mean not having autosave is acceptable, because one relatively stable version in a long chain of miserable bombing IDEs from -um- 1990 something up till now is rather an indication that this will be the exception and not the norm.
