PR Summary 📝

Let's cheer for these awesome improvements! 🎉😃

• User Interaction Enhancement 🖱️💡 We have added a brand new property known as flags to multiple items within dialogpreferences.ui and pattern_piece_dialog.ui. This makes these elements interactive, letting users select and check them. Great for ease of use!

• Code Optimization 🧹🚀 The inclusion statements' order has been tidied up. We moved theme.qrc to be included in files dialogpreferences.ui and pattern_piece_dialog.ui for optimal organization. This keeps everything clean and easy to manage.

• Design Improvement 🎨💫 There's been a subtle change in the rectangle dimensions inside pattern_piece_dialog.ui. The width has been streamlined from 362 to 264 and height from 558 to 486. All about making things look just perfect!

• Additional Insights Button 🎯🔘 We introduced notchSubType_ButtonGroup to the buttongroups section in pattern_piece_dialog.ui. This gives more options and insights at user's fingertips.

An exciting update, isn't it? All these modifications are designed to improve the user experience and efficiency! 🎉🚀😄
