The save menu has been upgraded with the following features:
- Folder support
- Use filenames up to 45 characters
- Add descriptions to your schematics
- Rename custom components without having them disappear in your architectures
- Get a warning before deleting custom components that are also in architectures

Soon to come will be allowing nested components in the component factory.

Also a bug was fixed that might have caused your input or output component to get deleted. If you are stuck on a level with messed up IO components, do the following:
1. Go to the save menu and create a new schematic
2. Copy paste your work to the schematic
3. Delete the old one
