Seanau Icon Toolkit is a unique, yet easy to use icon editing and style tool, which allows you to create icons quickly and professionally with little editing experience.
Seanau Icon Toolkit has 13 revolutionary stylized filters that allow you to create a highly stylized icon in just a few clicks. You can create various styles such as iOS, Vista, Mac, origami style, crystal style and more.
Seanau Icon Toolkit's native image format is SITF, which is used to save your graphic elements, so you can edit them in the future.
The app lets you to work with multiple layers simultaneously, each of which contains an image which you can edit.
Layers which are empty can be modified by adding various shapes and colours etc. which then can be merged with other layers.
Unfortunately you cannot duplicate layers, but the Undo and Redo functions will still allow you to make other modifications and you can revert versions until you are satisfied with the one you like. Layers can then easily be enabled or disabled. This in-turn, lets you preview only specific components of your project.
