PR Summary 🎉

Great job, team! 🙌 Here's what we've been accomplishing together:

• Revamped Formula Editor Dialog:
  We have made some enhancements to the EditFormulaDialog constructor. It now accepts an additional parameter called source. This parameter helps it understand where the request is coming from, enabling it to determine which elements need to be visible based on the source. This not only simplifies our process but also strengthens our platform's flexibility and adaptability. 🚀

• Custom Settings for Each Module:
  We updated functions in the seamly2d, dialogvariables, and seamlyme modules to create a more customized EditFormulaDialog based on their unique requirements. This extra layer of customization in our modules will refine our application's overall user experience. 🌟

• Expanded Dialog Source Definition:
  We've added an enum value called DialogSource in def.h. This helps us identify the initiating dialog type for 'Edit Formula', crucial to deciding which tabs we should hide. This new level of control allows a smoother and less confusing interaction for our users. 🌐

• Update on Multiple Dialogs:
  To implement our new feature, we adjusted the instances of EditFormulaDialog in dialogspline.cpp, dialogsplinepath.cpp, intersect_circles_dialog.cpp, intersect_circletangent_dialog.cpp, dialoginternalpath.cpp, PatternPieceDialog.cpp, and vabstracttool.cpp. It's amazing to see our updates swiftly integrated across our different tools, making our application more consistent and intuitive. 😊

Fantastic job, everyone! These updates streamline our workflows, improving our application’s agility. Let’s keep up the great work! 💪 🌈
