I have lost many hours of work constantly because of light forgetfulness and my outlet is on a timer and I would have to redo everything.
If the program could autosave about every 30 minutes (Default), that would be a lot of help.
The option to change the auto save time would also be good for people with stricter or loser schedule. (Like in Minecraft X-Box 360)
They could be a little notification or they could pause what you are doing, but I think it would be a big help not just to me but to other people.
