The immense resolution of the retina macbook pro (2880 x 1800) is now supported. The exported png's are indeed on the large size about 4mb. My laptop ( with 1/4 of the retina screen estate 😐 ) experiences some performance drops, hence the resolution only fits on the fastest macbook, which should handle it just fine.
Yesterday, Makeyourwallpaper.com reached the 1000 visitor per month milestone. I hope you all like the webapplication. I improved the dropshadow functionality, the dropshadow leaked on the inside of the border which isn't the case anymore.
I would like to hear, if you have any feature requests or improvements for the application. I am planning to create some generative art functions for the background of the wallpapers.
