Well, i'm develloping a project and i noticed a may be a "Bug".
How to reproduce:
insert image object. upload image, select image, now resize the object
image to height less then 4px, wont work, doesnt let me.
Another thing to improve would be textarea, textbox's, input's, select
list, they could have option to edit background color, that way could
user could actualy reproduce the psd slicing, and experience more
functionality in the way the website( mockup ) is done.
Keep the good work, i love this website.
Best Regards
Tiago
