########################### ### Todo John B ### ########################### Forces in potential tab - add vanderwalls and coulomb (attractive and repulsive) forces as option - 3 options as radio buttons: >Show separate forces >Show total force >Show none - make adjustments grabbable on graph, with some indicator that you can grab them. Look at other sims for this. - make adjustment sliders appear only when "Adjustable Attraction" is selected - add thumbtack to pin down left atom - remove "Stop Atom" button - add "Return Atom" box for when atom disappears off of the screen - change reset to "Reset All" - add little icons for molecules (just little blue, green, or violet spheres) - ??? ########################### ### Todo Noah P ### ########################### - icons for solid, liquid, gas - think of a better phrase for "separate forces" - redraw graph background - ??? ########################### ### To Discuss ### ########################### From Trish 9/4/08 First tab: One thing I thought would be interesting was to change the state to liquid and toggle between the substances. I realized that when I change substance the phase goes back to solid, but there is no indicator. When you select a phase, the button is outlined but not if you change substance. Second Tab: I miss having a particle counter and also get tired of pumping. It seems like a control like there is in the other chemistry sims would be helpful (Gas Properties, Salt, and Reactions all have particle number controls and counters). Also, I would like to repeat my thought that the Gravity control should be demoted to below the other diagrams. >>>NP: Particle counter seems like a good idea. Need to have a look at gravity slider. Third tab: I like the new sizes. I am not sure how the STOP ATOM button is supposed to work, why wouldn't a user just press PAUSE? Right now, it seems that once I hit it I cannot get the ball to move again unless I drag it. >>> NP: We decided to remove the Stop Atom button. ########################### ### Done ### ###########################
