Plenty of questions, most around support for things. Like editing SVG filters/effects in node-based manner. Could be done by
implementing the same protocol imgflo does towards the Flowhub UI: http://noflojs.org/documentation/protocol/
Also interesting q. about if trend towards more client-side image processing makes this work not so relevant. My answer: partly not, because image payloads still need to be optimized for size.
Though combined client+serverside is something that is interesting to the project, https://github.com/jonnor/imgflo/issues/24
