Tinker's Planner

Tinker's Planner is an addon to Tinkers' Construct that allows you to easily preview the stats of TiCon tools with any tool parts. This mod is entirely client-side!
This mod adds a blueprint icon to the Tinker Station and Tinker's Anvil and clicking this icon will open the Planner UI.

From here, you can draft out tools and view their stats.

You can bookmark tools you've "created" to reference later, as well as sort tool part lists by certain attributes (such as mining speed or durability). You can even generate random tool combinations for fun! When you're ready to create your final tool, you can "star" a bookmarked tool to pin it to the Tinker Station or Tinker's Anvil UI. From there, clicking on that tool's icon will try to automatically place the tool parts needed into the correct slots, if you have them in your inventory. It will also let you know what tool parts are missing or incorrect for completing the craft.
This mod is also available on Modrinth!
