When teachers start to really use a 32GB iPad, they quickly start to run out of memory, so you have start removing apps and providing self install options.
If you visit the app list for a device those apps that have been removed no longer show the amount of space the app requires. It only shows the amount of space that an installed app is currently taking up (this possibly includes sandboxed documents?). Anything that has been removed shows no size data (make sense since it isn't installed).
If you are making decisions on what to put back, you have no visible app size that can help you determine whether the app you could reinstall is too big. Even visiting the app page, you don't see a clear size estimate of the installed package.
So the suggestion would be to keep in the app list an italicised install size showing how much this app would take up should it be reinstalled.
Seeing the remaining space available on the device on this page would be also useful.
It could be useful during the reinstall workflow (ie. hitting the reinstall button) to give a confirmation of the current device memory size with the estimated memory size after installation as a double check - "Do you really want to leave this teacher with less than 1GB?"
