I just posted / uploaded an altered pet window for a friend of mine. This pet window is close to the default with a few changes.
- Removed all the dead space int he window, compacting it a bit.
- Shrunk the buttons (21x21 instead of 28x28)
You can find it listed here
Let me know if there are any issues with it as normal. Also more parts to come for her UI, as she wants them altered.
