Steps to reproduce the problem:
1. Set your Undo Times in Preferences to 100 for safety.
2. Spend all day tediously animating a project with tight deadline, saving your project throughout the day as you progress.
3. Mistakenly press CTRL + S (Save project) out of habit after accidently deleting all your keyframes in Curve Editor.
4. CTRL + Z (Undo) to retrieve your keyframes in Curve Editor.

Actual Result: Lose a day of work and a client. The Undo Times are not accurate to the value entered in Preferences.

Expected Result: That a $800+ self-proclaimed "professional real-time 3D animating software" would have a BASIC feature such as auto-save.

I've been searching through forums and docs and can find "iClone Autosave Feature Requests" dating back to 2010!
How is there still NOT an autosave feature?!

At the bare minimum, the undo history shouldn't delete after saving.
