I've been learning how to import images onto separate layers and create images of multi layer combinations from first loading as tracing image and then converting to a separate layer. I cannot seem to find a way to adjust the images on separate layers or navigate them around for placement.
Now this might be an expensive addition to the program and cause a significant price increase. This would be a nice feature for me considering the way I work with art rage. I have a tendency to create objects in a lot of different files over time, and then combine certain objects together for a composition. I then proceed to either adjust opacity of the layers and drop where necessary leaning to the palette tool for some blending, or I will erase certain areas of one layer so that other areas appear through the erased hole to get the composition of objects unified into one piece and then drop layers and attend to blending and smoothing adjustments. Sometimes the images I import are not the same size or need movement on the canvas to a location other than where it appears automatically by importing through tracing paper and then converting to separate layer. It would be a nice feature having the ability to take layers and adjust the size and navigate that one layer around the canvas. Of course this may be something that is not practical without a significant price increase. I'm sure that attending to one user is not as important than hundreds of users that prefer to keep the price low and affordable.
On the other hand if no problem or added cost this would be my suggestion.
