 +  * **Krita is far better than GIMP in many ways and beyond**
 +    * https://krita.org/en/
 +    * it, at the same time, aims to be a free alternative to Corel Painter and PaintTool SAI
 +====== From Photoshop to GIMP ======
 +
 +**updated 2016.11**
 +  * **Quick Conclusion for Photo Retouch**
 +    * for lack of adjustment layer, it is hurting the fast workflow for non-destructive photo retouch workflow
 +    * it has clone, and basic heal for 2nd layer retouch, but lack of quick spot heal and patch tool may slow down the retouch process a bit
 +  * **Quick Conclusion for Graphic Design**
 +    * lack of "mask unlinking feature" and "quick multiple layer selection" are slowing the arranging layout process
 +    * same, lack of adjustment layer is quick no no for fast multiple alternation version creation.
 +    * text is not able to keep editable after rotation or scale, and lost vector graphic information, which means big No No for graphic design.
 +  * **Quick Conclusion for general usage for image editing**
 +    * it has all the essential tools for non-professional graphic user to get the job done.
