have you ever worked on photoshop, 3d studio max, etc? These softwares have an autobackup feature. And here's how it works: you set the autobackup to AUTO save every 15-30 min. And then, the software automatically SAVES your file. This is usefull because if you are working on something and the program crashes out of nowhere, you have at least a save file created X minutes ago.
In Construct 2 we have two options. Correct me if I'm wrong: autobackup, that create a backup file when you save your project, and this is usefull in the case that you messed up with something at your game and want to go back to last save. And we have scheduled autobackup, that does exactly the same, but saves on other folder. I'm not saying this features are bad, they are very good. However, when I saw "autobackup" feature, I thought it worked like 3ds max, photoshop, etc.
So, in short, I would like to have an auto-save feature, so I don't lose my job if I forgot to save and C2 crashes.
