Upmock is dead, long live Upmock (My OS web design tool)

maybe OT but my current workflow for doing mockups is by using jade + mixins for bootstrap + http://tin.cr/

for me its faster to use vim to bring some bootstrap components on the screen (in that stage i don't care about the structure of my HTML), apply classes to make them postition: relative and use the chrome developer tools to move them around, apply colors, ... and through the magic of tincr it gets persisted into an css file.

so i use the best of both worlds, graphical tools for stuff that is hard to do with code, and a texteditor for stuff that is faster to do by some lines of code.

bonus point: even if i throw the mockup away i still can reuse some html/css snippets when i start with the real implementation.
