Update 2023-11-04 - States!

Changes:

• The "Hotkeys" menu has been renamed to "States".
  • States can now be triggered with a schedule, in addition to hotkeys.
• Added a "Hide with parent" option under the Motion Parent settings.
  • On by default.
  • When the parent is hidden, layers will be invisible even if their own visibility is true. This allows for many layers to be hidden at once, and opens up scope for combining the effects of multiple States.
• Stability improvements and bugfixes.
• Included VC_redist.x86.exe for convenience to those who might not have the x86 Visual C++ Redistributables installed already.

Below: A gif demonstrating the use of two states on scheduled timers. One state alternates between two groups of layers for character moods (neutral vs relax). Another state alternates between both sets of the "arms_gaming" and "arms_idle" layers on a shorter interval. 
All the "relax" layers have "Edie_body_relax" as a parent, so they hide when it is hidden (and the same setup for the "neutral" versions).
