Hello, first I wanted to thank you for working in this project! It has helped me very much at Purdue!!
BUGS:
I can't copy and paste values into the variable columns. This seems strange. It works on Libreoffice spreadsheet. It's very important for students to be able to paste values (similar to importing values from a text file but this way is faster!).
I can't manually input values into the variable column just by hitting ENTER key. I have to often click on the value cell first, then it allows manual input. This happens for most cells. I'm certain that is a bug.
Finally, when I rename the variable column, it often returns to the default name. Strange.
Getting values into the variable column is so important. :-(
Many thanks and I hope this helps.
Joel
