Background remove is not high quality: It keeps only a little from hair.
Remove background also brings back small images 1200px only.
After removing background, there is a limited option to add a color background limited to only 9 colors & no option to choose my own Hex/RGB.
There is option to replace background with a limited 15 images, without any option to add my own background image & without any option to move the object around.

The Inpaint feature function is also limited & works well only with small simple objects.

On Image enhance I almost always get "System is Busy" failure.
The colorizer is also very limited & with similar error.

Filters are limited & have no advantages on free software or online free sites.
They give no option to balance the filter layer & have no advantages.
Even the free version of apps like Ribbet offers much more editing & filtering options.
