Re: Re: Re: v6: still no multiple undo?
Having a save after each evaluation is hardly sufficient: as it seems to be set up, each new version replaces the last. This is dangerous in that a huge amount of work could still be too easily lost. A usable substitute is a 3rd party general utility, such as CS-RCS revision control system or, more simply, a multiple-version backup imaging utility. (On my Windows system, I use a PC Magazine utility Insta-Back, where I can specify what folders and files to back up and how many levels to maintain.)
