Feature Request: Allow user to set breakpoints for sliders

Currently, the slider breakpoints for responsiveness are hardcoded. This doesn’t really work in all situations, especially since displays go up to at least 4K these days. I changed the source code for the plugin on my local development install to add a breakpoint selector in the editor and then the slider js gets the data the same way it gets the number of slides from the div data. It works great. It would be nice to have this a regular feature.

Also, it would be nice if we could have user editable templates for the grids and sliders that can be placed in the theme directory that override the default plugin templates.
