Few things to consider
These stencils are available only for OmniGraffle. We need to to find if there's a equivalent for Visio or Powerpoint available?
Or find ways to convert them to use it for the other tools.
These stencils aren't named as in the Sencha Component Library, but the screens created using them could be used to easily identify the corresponding elements while developing.
The elements are not exhaustive, but covers the basic and it is important to identify the ones that are needed and not available, with reference to the Sencha library.
"if we can get these stencils rolled out to all of the designers (meaning we’ll need a non-Omnigraffle version), and we can control which stencils people use, it will start to introduce consistency by default!" - Susan Wolfe
