Hi,
The word popup tool is great. Really great. Boy, I remember the old days of Skritter when we had to walk 6 miles to the computer lab just to use it. Kids today have no idea how sweet they have it.
I'd suggest it should not, however, that the add parts list that pops up should not inherit the current state of what one is studying. You should be able to click to add all parts, even if you are currently just drilling on tones. I generally do one type of a drill at a time. (Actually, first I set for Heisig keywords, cram my Heisig list, then turn Heisig off, move to study everything, and cycle thru each of the four drills.) I use the pop-up tool to add components of characters I am already working on, but when I do that, I can only add the part/drill that I am working on.
Cheers,
Thanks.
