What do you like best?
Ease of use. It is intuitive and has a user-freindly user interface. When I started using Pixelmator years ago I can recall picking it up very quickly and feeling comfortable with the software much faster than when learning Photoshop.
Also, if I start a design in Pixelmator and need to work on it in Photoshop later, I can just export as a PSD. I find that most layers tend to convert exactly, but not 100% of everything. Still a great feature.
What do you dislike?
Not being able to snap my various tools, layers, and effects windows into a grid/snap with the project window. Photoshop is setup this way where everyitng can be drag + drop locked to it's own spot. Pixelmator has all your tools, layers, effects windows free to move at all times. This is handy, but I would like the feature to snap them in to the edges sometimes also.
It could use continuous improvement to all features and adding additional tools. Improvement could be made to PSD export to be very precise when it comes into photoshop without loosing any effects or changing any layer types if absolutely possible
Recommendations to others considering the product
I recommend this as an excellent tool to add to any graphic designer/web designer's toolkit. It can be very good for quick design tasks and image edits/processing and modifications as are numerous in website/wordpress and less-complex graphic design projects. It is a great multipurpose design tool that I find I am able to work in quicker and easer than any other design softwares without having too many extra features in my way to clutter workflow.
What business problems are you solving with the product? What benefits have you realized?
Excellent for efficient and speedy graphic and website design. Especially great for website design. Print design it is limited. Adobe Indesign tends to be my go to for print design formatting prior to print, but Pixelmator is my best tool for whipping up designs quickly with a very intuitive interface. A lot faster for me than Photoshop.
