Hello Andee,
Thanks for reporting that the “Open in Draw Tool” option is grayed out when CODAP is running on an iPad. I just verified that you are correct, but it can’t be because the draw tool doesn’t run on an iPad because you can open it from the Plugins menu and it works fine! Investigation is required!
There are quite a number of “small” things that don’t work well or at all on iPads, but I don’t have a comprehensive list. Just to give one example: On desktop you can click and scroll in a case table to select a range of cases, but this doesn’t work on an iPad.
The most glaring difference, I think, is that on touch devices you mostly get get the “mouse hover” tips. One place you can however is by “touch and hold” on an an attribute name in a case table—this brings up the attribute description.
Sorry I can’t provide a complete list.
Good luck with your workshop!
Bill
