  1. in vistrails, input the directories by navigating to them in the usual fashion as all other mac programs, but leave the option to type/cut/paste if possible
  2. a box with an error message should pop up if something is wrong with the path or the files
  3. the vistrails window should remain responsive during the conversion, show a progress bar and a cancel button, not just freeze up
  4. a box with an error message should pop up if something goes wrong with the conversion
  5. there should be some sort of altert (a dialog box in front?) when the conversion is done. I need to do other things while it is working and the vistrails window gets buried somewhere
  6. the "Fire demo visualization" should already know where the vtk files are, not ask again (or it should prefill the choice with the known location)
  7. make it simple to recover or backtrack when something goes wrong, including wrong user input. Make every step guaranteed re-runnable. I had to start from the scratch (exist vistrails, start again...) every single time when I messed up, which was quite often.
  8. Why all those boxes? A scientist probably does not care about the details, certainly not the first time. Just show the user one big button, the user will push the button, navigate to the directory with the wrfout files, watch the progress bar for a while, and then watch the movie. Or at most two buttons (convert, visualize), and make it clear in some dialog box or in the howto how to save and visualize the next time without converting again.
  9. There should be online help, or a help button to start the preview of the pdf of the manual. The pdf should be installed in the VisTrails application directory, where VisTrails.app is.
  10. it needs to be clear how to start a spreadsheet. The spreadsheet should pop up and not hide under the vistrails window.
  11. the axes in the visualization should be labeled and the current time displayed in every frame, please.
  12. The control buttons on the bottom should give some feedback when pressed. The movie reacts slowly (or not at all at times), so it is not clear what is happening
  13. The user interface is a bit raw and doing strange things at times. The look and feel should be the same as other native Mac applications. Probably VisTrails is not using the right Mac library for the GUI?
  14. The GUI should be really simplified to get the user hooked the first time: simple useful things should be done in a simple way, without studying anything. Then, if someone wants to get deeper, they can do that later.
  15. The Howto should say how to save the movie as a file.
  16. I'd like to display the heat flux instead of/in addition to the area burned (I think that's what vistrails displays now). Please see the attached pictures. (This is from a new feature, ignition points moving along lines over time.) Vistrails has some artefacts but I know do not have the current version of the files. Will retest after I get it.
  17. It would be good to have some usual options, best from drop-down menus, such as: selection of variables, colors, transparency, start/stop time, play in a loop or not, add legends, labels, colorbars, etc.
  18. I could not find controls for rewind/advance and start/stop capture to a movie file.
  19. I can see the ultimate goal may include the server in a kiosk mode, with the user just pushing buttons and choosing from menus, with all the details of the internal working and anything the user could mess up hidden and disabled?
  20. What is animation delay, please?
  21. I would be nice if the controls are not be visible in captured images/movies.
  22. during the conversion, vistrails seemed to disable other windows or steal focus from them (Chrome, in particular, where I am writing this)
  23. After the conversion, the vtk were nowhere to be found (I did not create the directory, but Vistrains did not complain and just went ahead with the conversion?)
  24. it was not clear what exactly it means "View the spread sheet to interact with the visualization" in the howto. I forgot since the last time. There is no button labeled "spreadsheet". The manual says something about main menu or spreadsheet toolbar but I did not see any such things in the vistrails window either. I was afraid to try and push random buttons for fear I would get to some state I could not recover from, and I would have to start all over again (another hour or so). Eventually, I accidentally found the spreadsheet hiding under the vistrails window.
