With Firestorm becoming as popular as it has, creators (particularly furniture creators) have started to include "To resync press CTRL+S" in the text area of their animation menus, of course this only works in Firestorm. There are few (only one I am aware of) still including a "Resync" button in their animation menu. (Or they force a periodic resync, which is somewhat interruptive.)
Please consider implementing a CTRL+S feature that, like Firestorm, causes animations to resync. This would make the viewer much more user friendly!
