v2.1.0

• Fixed save delimiter issue (The delimiter between the group and the data is no longer a space, but the predifined)
• Added empty checks for text inputs
• Refactored the file structure: separated the main code from the input handling and the windows

Warning

The previous version is not compatible with the current one, because of the delimiter issue.
