- Better handles unexpected exceptions
- Expected exceptions should be OperationException
- Leaves files unchanged even if the exception occurs at *any* point of the operation
- TODO: Probably have to optimize this.
- Operations now operate on IList<T> instead of List<T> to maintain compatibility with AvaloniaList<T>
- Slightly better comments
- 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)
