Why is Gnome Crystal Viewer is poorly designed?
I am not an idiot. I have a masters in Geology so I know what a crystal unit cell is and the general concept of specifying dimensions and bond lengths. So why is Gnome Crystal Viewer so hard to use?
It insn't that the obvious things aren't covered in the onlie manual and it isn't that the software should be educational, although given the audience for Ubuntu, maybe it would get the authors more praise if it were. It is little things in the design, prehaps GNOME features in the design, that make it hard to use.
First, there are no working data files that ship with the package, so at least if you wre going to figure out how it works, you might load something to look at and dissect. That ought to be easy to fix. Why not a library ofcommon substance examples, minerals and salts, and some simple organic species?
Second, if you make a mistake the GNOME app penealizes you by resetting the form. It doesn't remember all that you selected.
For example. I wanted to set up the structure for a simple ionic salt, NaCL, which I know has a cubic unit cell. I don't recall the bond lengths or coordiantion, but I expect some help from the application for that. I kept having to respecify that the bonds are ionic because when I made a mistake the form reset that to Unknown. I finally gave up. This app needs major attention to details.
Finally, the feedback feature in Software Center, or is that Crntre, is obstructive. It asks for email and password, which if you get one wrong, you have to type the secret words over. I hate those secret words because I am visually impaired and seeing and typing those is quite taxing. That is why I am posting feedback on the app here as a question, out of frustration with the Software Center.
