This is a pretty neat mod. Haven't seen any activity in this thread for a while, thought I'd add a new twist to it. The original mod didn't add floating names to plants or mushrooms. Probably for good reason. Not really a point to add floating names to flax and mushrooms as different varieties are generally not mixed up together. But since this mod came out, there is now Bountiful and Rich plants that might make it worth it now. It might help you spot Abundant (Rich) and Bountiful (Motherlode) varieties of resource nodes of Flax, Kenaf, Cotton, Ironsilk and Steelsilk that are near you.
Whats really neat about the mod is you can find a particular gem, when multiple kinds are mixed up. Additionally, you can spot the Rich and Motherlodes nearby. It also puts floating names above the wisp residue (screenshot of the residue is in the first post of this thread, OP).
If you don't like the names above the plants (flax and mushrooms), then just delete the two files that begin "plant_" in the filename.
Just unzip to your main game folder (Likely C:\Program Files (x86)\Istaria )
