Some feature requests:

IsYou have an online simulator. It'slinked at the top, but I missed it. It would be nice to add a link in ech example to the example runing in the simulator.

I tried the simulator, but I can't see the moving electrons/holes. Also, in the diode simulation, how do I reverse the battery?

Isit posible to show arrows that show the total current in each electrode? Since electrons and holes have different charge, it's hard to see the current. (IIUC the simulator can show the number, but not draw an arrow. So this may be hard to implement.)

1. I wouldn't be able to do that because these examples are only available in the desktop/steam version.

2. Again this is feature is in the desktop version only (check "View charge carriers"). You can reverse the voltage source by setting the voltage negative.

3. That's a nice suggestion, I think I'll implement it in the next release.

I have no plans to update the web version any further.

I used the online simulator for more time now. More random remarks:

>> It would be nice to add a link in each example to the example running in the simulator.

Why it is not possible to add the examples? Is there any technical problem or just lack of time?

>> I tried the simulator, but I can't see the moving electrons/holes.

> This is feature is in the desktop version only

I din't notice that the online version has less features. Perhaps add a fake version number like "Online simulator 1.0" and "Desktop simulator 2.0" or "lite" vs "pro"

>> Also, in the diode simulation, how do I reverse the battery?

It took a while to notice that a new slide bar appears when I click on the battery.

Also, it was very strange when I change the border from absorbing to conducting.

When it shows the current, all of them have the same length. I had to tweak a lot the "Vector field brightness" slide so the change was easy to see.

I had to tweak a lot the "Vector field brightness" slide so in the "Bridge rectifier" example I can only see the current in the two correct diodes.

I made a few graycolor graphics a long time ago, and I remember that I had to pick correctly the gamma or saturation. To get a nice drawing of a function f between 0 and 1, I had to draw something like 255*f(x)^2 or 255*f(x)^(1/2) otherwise the points where f(x)=.5 look too bright/dark. I don't remember which of the version was the correct (and the other is stupidly wrong). Also, the exact power instead of 2 is like 2.2 for PC and 2.4 for Mac (or the other way around, or something like that) and I think I had to tweak it a little to get the best result. In conclusion, it may be nice to have yet another slider.
