The Line Styles and Line Patterns dialog should be combined with a few tweaks :
- provide a button for Merging selected Line Styles into another
- provide a button to Purge unused Line Styles or Patterns
- combining the two dialogs would allow a graphical display of each Line Style at the right, with easy access to editing the Pattern (at the moment it's hard to know what each looks like without a lot of trial and error)
Also, adding the preview to the Detail + Model Line Creation list would be beneficial (though it might be processor demanding, this feature works fluidly on Archicad).
