Inactive document tabs get a faint outline so neighbouring tabs stay apart, and the Home tab uses the same hover tint as the design tabs so its label stays readable in the light theme. Fixes#1115.
Sketch Mirror, rectangular and circular Pattern, and Offset now show a green live preview that follows the selection and settings; OK commits, Cancel leaves the sketch unchanged. The shared dialogs show the current selection step and source counts, sources can be toggled with Ctrl/Cmd-click, cleared and reselected.
Offsets keep editable driving distance dimensions (One Side, Two Sides, Symmetric) that update the derived curves without moving the source, with undo/redo and save/reopen. Format 19: older files keep their fixed offsets.
New dialog labels in en, zh, ja, de and ko.
Fixes#696. Fixes#517.
