Worthless-applies blur to your drawings every time you save!
In terms of a drawing tool, this has nice features. But this is rendered worthless if when you save your file, the next time you open it, its blurry. Every single file Ive saved has been blurry the next time Ive opened it! If you save multiple revisions as you work, it gets blurrier and blurrier. Stupid and useless. Would be 4**** if it let you save your drawings without destroying them with a permanent blur filter.
