What does Dwarf Therapist let me do that I couldn't do in the game?

What does Dwarf Therapist let me do that I couldn't do in the game or manually in a spreadsheet and tediously in the native client?

From gaming antony.trupe

• Taken from the project on Google Code

  • Persistent custom professions - import and manage any number of custom professions across all your forts.
  • Assign multiple dwarves to a custom profession at once to unify active labors
  • Manage labors and professions much more easily than in-game using a flexible UI, allowing quick review of all dwarves at-a-glance
  • Display all pending changes before they're written to the game
  • Sort labor columns by associated skill level
  • Persistent and customizable display; change colors, reposition/hide information screens
  • Group your dwarves by several criteria
  antony.trupe : none of these things I couldn't do by looking up all the information in the game, manually entering into a spreadsheet, sorting, and updating through the client, right?

  antony.trupe : thanks for the answer btw.

  JavadocMD : @antony.trupe It doesn't directly do anything that you couldn't do in game, certainly. It does provide features that reduce tasks that in-game might require 100 keystrokes and reduce it to a couple clicks.

  tzenes : @JavadocMD much the way glider reduced WoW from 100s of keystrokes to a couple clicks...

  JavadocMD : @tzenes: Haha, I wouldn't say *quite* the same way.

  tzenes : @JavadocMD I realize that was a bit of a specious comment, but the point I was trying to get across is that reducing the tasks in DF is like using a car to win a Marathon; kinda defeats the purpose.

• Dwarf Therapist's Vision

  "What DwarfTherapist is not:

  DwarfTherapist is not intended to undermine the game designers’ intentions of how the game mechanics, balance, or logic works and as such DwarfTherapist as not a hacking, cheating, or ‘game modding’ tool. DwarfTherapist also is not intended to create a ‘game outside of the game’ in manners that extend game functionality (such as command-chaining or macros) or otherwise introduce new gaming elements outside of Dwarf Fortress that are not immediately and conspicuously tied to the primary and secondary design intentions."

  tzenes : I'm curious as to who downvoted this. The reason @Antony put this here is because he doesn't believe this to be cheating (as I do). While others disagree it is certainly "on topic" and not worth a downvote.

• It let's you save 30+ minutes when managing 80+ dwarves.

  More Time Playing, less time managing.
