I'm the developer of A-Dock, so if you have any complaint, please email me, so we can discuss the issues and find ways to enhance A-Dock to fit your needs.

- The icon size is handled by the Theme. So you're right, I should label the icon size slider "Tile Size" slider.

- Fully transparent background is not possible to achieve (at least without any ugly patch) to keep drap&drop working.

- As for the sluggish drag to poup folders, please give me some details.

Thanks
Jérome
