I said I would never do a slider.
So, this isn't a slider, it's just something which looks like a slider, acts like a slider and happens to be called a slider...
Important Information
I have managed to implement the new slider functionality without introducing any additional queries.
In doing so though, there will be an error generated once the new files are uploaded and until the installer is run: Mysqli prepare error: Unknown column 'slider_date' in 'order clause'
Ideally you should disable the add-on before uploading the files, and re-enable it once you have upgraded.
Regardless of how you upgrade, the error can be ignored as it will only be generated between uploading the files and upgrading the add-on.
