I opened a medium complex SVG and the app became unresponsive beyond useable.
After scaling it down by manually entering the scale values I could not find the SVG any more (the Align... buttons in the top bar are always grayed out/not implemented yet, it seems).
Every update (even moving the canvas around takes 1-2 secs on my laptop.
TLDR; looks like this is redrawing everything every time which makes it useable only for very simple projects atm, unless I miss sth. I.e. needs caching of vectors as bitmaps/textures of some sort.
Also doesn't seem to support OpenEXRs yet? They won't show in the file browser.
Screenshots look great and I love the node editor's mapping to the layer stack.
But as always with Graphite it's still unclear to me how many of the screenshots show actual functinality and how many are mockups or the functionality behind some UI elements is simply not implemented yet.
