If you are here looking for Skillet on Classic then you can find it at Skillet-Classic.

Other than "Please open an issue" I won't be responding to bug reports in comments.

Features:

• Larger the the standard tradeskill window
• Built-in queue for creating multiple, different items
• Queued items are saved when you log out and are restored on log in
• Automatically buy reagents for queued recipes when visiting a vendor
• If you can craft a reagent needed by a recipe, then clicking on that reagent will take you to its recipe (same features as Reverse Engineering)
• If the item to be crafted requires a minimum level to use, that level can be displayed along with the recipe (disabled by default)
• The shopping list of items needed for all queued recipes for all alts can be displayed at banks, auction houses, or from the command line
• Items needed for crafting queued items can be automatically retrieved from your bank or guild bank (by using the shopping list)
• User editable list of notes attached to reagents and crafted items
• Queued counts added to (optional) notes display
• Crafted counts can be adjusted with Right-click and Shift-right-click on the item icon in the detail frame
• Recipes can be filtered by name, whether or not you could level when creating the item, and whether or not you have the mats available
• Sorting of recipes (name, difficulty, level, and quality of crafted item)
• Tracking inventory on alternate characters
• Plugin support for (limited) modification of the Skillet frame by other addons
• Custom grouping
• User managed Ignored Materials List
• Complete or mostly complete localizations for deDE, esES, frFR, ruRU, koKR, zhCN, zhTW

Compatibility:

• TradeSkillMaster Skillet can be used with TSM
  • If the TSM Crafting UI is set to 'WOW UI' mode (use the 'WOW UI' button and then close the TSM UI)
  • If the Skillet Appearance option TradeSkill Compatibility is checked. Note: Skillet frames have strata and background changes in this mode

FAQ:

• What are the numbers in the middle and how to hide them?
  • Blue = How many you have
  • Green = How many you can make from materials you have.
  • Yellow = How many you can make by crafting the reagents.
  • Orange = How many you can make if you purchase materials from a vendor.
  • Purple = How many you can make using materials on your alts.
    Right-click on the bag icon above the numbers.
• How to search in the item name only? - Start your search phrase with exclamation mark: !ink
• How to search in Auction House? - Alt+Click on shopping list
• How to retrieve items from bank? - Turn on "Display shopping list at banks"
• How to turn off Skillet temporarily? - Shift+Click your profession button/link. It also works for View All in your Guild Tab.
• How to use Enchanting Vellum? - Right Click on Process/Create/Create All button. You create only 1 enchanted vellum, repeat to create more
• How to paste a recipe in the chat? - double click on the recipe list
