Lasso-select TurtleStitch Snap! автор Jacob Tekiela

Tired of deleting or moving blocks one by one? This extension introduces a highly-requested rectangle lasso selection tool directly into the Snap! and TurtleStitch workspaces. Click and drag to draw a bounding box and select multiple blocks or comments at once. Hold Alt/Option to toggle individual blocks in or out of your active selection. Quickly duplicate, move, or press Backspace to eliminate entire groups in a single keystroke. A massive time-saver for large block-based projects!
