ToonSquid's latest update includes numerous keyframing workflow improvements and a noticeable step-up in the shape assist accuracy for curves, ellipses and polylines.
You can now proportionally scale the timing of a selection of keyframes.
You can now reverse a selection of keyframes. This also automatically reverses their respective easing curves.
The new Step setting for easing curves lets you define the rate at which keyframes should be interpolated.
ToonSquid can now automatically hide all layer properties from the timeline that don't contain any keyframes.
You can now perform keyframes edits such as drag and drop, copy and paste, deletion, insertion, stretching etc. for a selection of keyframes that spans across multiple animation layers.
You can now edit multi-selections of animatable layer properties at once without the other properties getting deselected automatically when bringing up the actions menu.
Previously, the keyframe umbrella row was only shown if a layer had any effects. Now you can choose for this row to always be shown in the timeline, letting you quickly select and edit all properties of a layer in the timeline.
You can now customize the duration for which you have to touch and hold on a selection of keyframes before you can drag them to a different frame in the timeline. The default duration has also been lowered slightly for a more responsive out-of-box experience.
You can find this setting under Settings > Gestures > Keyframes > Drag and Drop Hold Delay.
