The Tool Library was the product of someone requesting a way to re-use tool definitions in the first place. A lot of changes and new features are the result of user feedback, the more the merrier! I can't promise that every idea or suggestion will make it into PixelCNC but users will have ideas for things I never would've considered - and there's a lot of value to be had from that.
I'll try to add in the ability to directly choose tools for an operation from the library dialog for the next update. Then you will always be able to go back to the Project Tools mode and edit the tool definition if need be, or otherwise use the Project Tools mode to populate the library and update definitions the way it is now.
