I beg to differ, every app, tool or otherwise deserves to look better / good / different etc. with that in mind here (attached) are the whole 10 sprites needed to pull off the sample look in my above post.
Notes:
The TopBar sprite is 28x28 and should be resized to match the length of the screen (maintain it's 28 height).
Same for the SidePanel sprite, resize it vertically to match the height of the screen (use sprite sorting to place it under the top bar.) if you convert this sprite to greyscale, you could use the colorsprite command to make it any color.
Planing ahead (and just in case) the slider bar uses a 50% black and white for the highlight and shadow, so it will work on any color underlay.
the 'buttons' and toggle' are pretty much self evident. Text should be applied over them and might I recommend the free custom font I posted a few days ago in this forum.
That's about it. and yes, I can and will help with any UI needs you might need/want for your scene builder. (just pop me an email.)
Cheers!
