- Overwrite might be a bad example, because it has no fail conditions. The intended behaviour for those is to throw an exception for invalid parameters, with an error text describing to the user what went wrong.
- Fail condition check may be moved to a seperate abstract method, forcing implementers to at least give fail conditions a thought.
- Minor refactor
- TODO: Better folder structure to group operations (Looking for suggestions)
- You can now open a directory
- The current filenames and previews are now displayed in the listboxes
- Added method pipeline for updating the lists (OpenDirectory -> Filter -> Preview)
