Looking for a mockup tool such as one listed in "Balsamiq mockups alternative for building wireframes?", "What collaborative wireframing / UI mockup tools are out there?" and "Web UI prototyping tools"
However, I need a tool that will work with Hebrew and Right to Left screen orientation. I've checked Balsamiq Mockups (web demo) and couldn't do Hebrew there.
Also looking for a comparision of such tools, including Sketchflow.
I've never properly tested it but I believe that WireframeSketcher handles Right to Left screen orientation. This is because it's based on Eclipse and Eclipse has a proper RTL support.
