So, I am starting a fairly complex private project, and would like to do real, professional, requirements gathering & tracing, just as we do at work.
I am looking for something gratis for Windows which covers as much of the functionality of IBM Rational Doors as possible.
- unique Id for each requirement
- linking of requirements, also between documents
- sort, search, filter (colo(u)r)
- insert images
- scripting language not required, but I won't complain about it, or any other bells & whistles ;-)
Since I can Google too, I am hoping that you will only answer with something which you have actually used.
[Update] I found http://rmtoo.florath.net and https://github.com/jacebrowning/doorstop both of which are command line based and work on plain text files. They do have some good features and may be of value to you, but I will continue to search for something GUI based.
[Update for bounty] I am offering a minimal 50 point bounty, just to get attention, but will award more for a good answer.
Please be aware of this question and don't post anything mentioned their, either as comment or answer, nor anything already mentioned here, unless you can expand upon it greatly. If I don't get an answer, I might consider coding one myself, either from scratch, or as a GUI for one of those two command line only tools.
