I want to request new plugit like animation switcher or add new features in animation switcher plugit.
but the animation can only switch to another animation after it end.

for example:
i have default action, 1.action & 2.action (in animation switcher)
A-key --> 1.action
S-key --> 2.action
On start, play default action, then press A-key to play 1.action, (the 1.action only play after default action play until end)
then, when 1.action is played, press S-key to play 2.action, (the 2.action only play after 1.action play until end)
