for me FNEI look more weird, It just give up to show item name

The FNEI seems to not display names that don't fit (at least that's an explanation that fits my observation). It does on the right panel, but doesn't on the left. Probably an issue with the new gui system (I've seen others related to clipping, so I wouldn't be surprised). I don't know how to resize that window however.
On the plus side at least it has a tooltip with a name when you hover over it.

I'm inclined to believe that it's a more general problem because it happens with a few items from pyanodon too (conincidentally, ones with longer names...).

Fixed in the next version.
