I like it. I think the animation of zooming in is easier to use than the instant zoom. I think instant zoom is jarring and disorientating sometimes as it's a sudden shift to a new image. Whereas the zoom animation helps track the zoom focus easier and transition from normal to zoomed. I added it to MeseCraft after testing this out a bit. I'll test it more and if it functions well, it'll probably stay in that game/modpack. Thanks!
