Restoring from a backup file does not restore
When you load a backup file from "Restore" in the menu, you will see "Restore complete" in the status bar, but nothing really takes view. This will be fixed in the next version.
If you want to restore manually, exit rastil once. Look for the backup file "rastail_yyyyMMdd.zip file to restore". Since this file is simply compressing the files and folders below the project, expand the file and overwrite it with the project folder you are currently using.
