Need Help Creating Palletes for My First Char

[Miru]

Currently, I am creating a Street Fighter Alpha 3-styled Felicia for MUGEN. One thing that obstructs me right now (and indeed, it obstructed me with creations of MUGEN characters previously) is the creation of palletes. Currently, I've imported my sprite and it made a pallete, but the magenta is not set to be transparent and I don't know how to make the pink transparent.

Well, I use GIMP, and I found the pallete re-arranging tool, but the problem is that the re-arranging box is so long i'm not able to click OK and save my changes. How do I set this box to a landscape perspective so I can save my changes?
