Re: your 3rd paragraph: yes, I wanted to mention that in my original comment and forgot. Thanks for bringing it up. A lot of our modern infrastructure comes from the almighty UNIX era- before GUIs had really become as mainstream as there are todays. In that era, things like "undo" were close to non-existent (there is no undo for `rm`- the GUI's "hack" to solve that is the "Recycle Bin" (which is also nonexistent on mobile, interestingly enough)). A lot of our modern web tools are mere interfaces to those various Unix utilities (phpmyadmin, as mentioned by Sacha, is just a neat little HTML interface to mysqladmin), and thus can't do much to provide functionality that's missing at the source.
