This tool is very useful to do fast and impressive graphics, but there are some hard limitations: lots of graphics have labels very limited by size (instead of having size adaptation for example), when switching from one model to another, we regularly lose a part of labels or icons (according to the number of text areas in one step), playing with color palettes is not efficient...

And the worst: there was no update or new feature since a long time.
It is a good tool but it may become incredible if the team could continue the work.
