Here is my current theme I made that I've been using for the stock GMenu2x https://sha.rest/C2zqPc
To use just copy the Waterv1.0 folder into /media/data/local/home/.gmenu2x/skins directory. Go to settings tab, highlight skin and press A. On the top line change skin to Waterv1.0 and press Start. Thats it. You can edit the font size under the icons if you wish by opening skin.conf with a text editor like wordpad and changing fontsize= from 10 to 9 or 11.
