New tool - Create Available Points Toolbox for ArcGIS

I have a new tool out that can be used to generate background/available points for habitat modeling (resource selection functions) in ArcMap.  It should work in ArcGIS Pro as well since it is entirely built within ModelBuilder and doesn't rely on any python. The user provides 1) their used points (e.g. occurrences), 2) a buffer from which available points can be selected, and 3) the ratio of used to available points. The tool will also combine multiple files into a single file using the filename to differentiate. This tool would be useful to wildlife biologists and others who work with radio-collar data and want a simple tool that runs in GIS. You can download the tool at https://www.arcgis.com/home/item.html?id=f5515ef257774ed790b9b64cf5d50fc5.
