Shifter

Shifter slides a single property up or down across a whole multi-selection at once, with a slider. It's the fastest way to nudge one value (brightness, a size, a speed) consistently across many effects.

Using it

1. Select the transformed effects you want to change (emitters, trails, and/or beams).
2. Open Tools → Shifter.
3. Pick the property and drag the slider. Every selected effect shifts together, live.

Because Shifter keys each object by kind, a mixed selection of emitters, trails, and beams is handled correctly, each shifted through its own settings.

When to use it

• Making a group of effects a bit brighter or dimmer.
• Bumping a shared size or speed across a scene of effects.
• Any time you'd otherwise edit the same property on many objects one by one.
