Another side project I'm currently in the process of designing:
Personal Problem: Me and my wife have some folders with so many random files. Too troublesome and time consuming maintaining it to be clean and organized. Pictures should be in a specific folder, installers in another one, etc. an example is the "Downloads Folder"
Solution: A small command-line utility that organizes a folder on where it runs from. This small command-line tool has only one parameter: a JSON file that contains "Rules" on what it will do on specific files. ex: .mp3's should be placed on a folder, .docs on another, etc. And so on and so forth. It could also come as an "installable" service/daemon that watches over folders. Still learning more about Scala, it's used in where I work, may write this command-line tool in that language for educational purposes.
