Sketch Plugin

We're looking to create a Sketch plugin to help us translate our files more easily. The Sketch plugin will need to: - have a Drop-down to swap between different all the different languages - be able to pull the content from the page, symbols and libraries - use .json files, Excel documents, or something similar to contain all the languages - use Keys/Labels to identity and populate the text field - be easily updatable We need something similar to the Polygot plugin - but the plugin app doesn't access Sketch Libraries - only what's included in the file [login to view URL]
