Zeplin takes and artboard and creates a hosted, interactive styleguide that is clickable. It's the ideal front-end development hand-off tool. FEDs can measure elements, get colors, fonts, etc.
- Craft is a toolbox by InVision that has some really novel features:
- Automated duplication. Handy for making lists, tables, grids
- Data generators. Names, cities, and custom things (I have one for grade levels and school districts)
Really handy tool for annotating artboards in sketch. I personally use Keynote for this, but the plug-in works well
Lightweight plug-in manager for sketch. You can search/browse plug-ins and keep existing plug-ins up to date.
A little clunky to install—but adds one-click "Send Slack" from Sketch.
