The previews of the pinned modules are too small to make out the details. Opening the dialog by clicking on them is fine and can be kept as is. However, in a lot of cases it would be nice to have a larger preview by just hovering over the pinned module.
Just to quickly check "was the h*** three or four voxels wide?". It's a little bit tedious to open and close the dialog all the time. (or maybe my memory is just not good enough ;)
