It’s frequently difficult to select multiple objects that either extend beyond the screen or sit on top of others - there’s lots of shift clicking. Drag and select only helps if you can enclose entire objects.
In several CAD programs (including AutoCAD) it works like this:
- Drag from left to right to select all objects that are entirely enclosed in the selection rectangle or lasso (window selection).
- Drag from right to left to select all objects that are crossed by the selection rectangle or lasso (crossing selection).
This would be great to have in Balsamiq.
