Version 3.44.90

Rewrote much of scripting engine and supporting V-code parts
Implemented scripting for layers window, settings toolbar, and tools toolbar (under Edit menu)
Name + ":" accesses widget's right-click dialog: "-e/tool flood: =10"
Freestanding ":" closes nested dialog: "-e/layer new w=100 h=100 : name=Layer1"
Fixed crash on errors in script
Fixed highlighting in layer list (damaged since 3.44.53, worse since 3.44.86)
Fixed preview of opacity gradients (since 3.44.72)
Fixed focus when starting with open dock
Fixed selection from script ("-s/all") not allowing width/height=1
Fixed pressure value for mouse with tablet enabled
