One of the things that has always been very confusing is, what have I preordered on prepub when there are "nested" bundles being developed. This is the problem specifically:
"Master Journal Bundle 5.0" is now available - I preorder it. It shows as gray, already preordered, if it shows up in a list.
But "Master Journal Bundle 5.0" includes 10 other sub-bundles that comprise it - also showing on prepub - but they show as available to preorder.
Now it may not always be obvious either, that a sub-bundle is in fact that - sometimes there is no easily discernible cross reference of name, sometimes compete lists of resources might not show, etc.
SUGGESTION: If I preorder (or order!) a bundle, any sub-bundles included are also grayed out. If I cancel the order so the bundle goes back to blue/available, the same should happen to the sub bundle. It would be even better if I hover over the sub-bundle, and instead of it just saying "You have already preordered this product" it said "You have already preordered this product as part of xxxxx".
