As this blog post says http://jacobfilipp.com/creating-choropleth-maps-with-google-maps/ , simplipy isn't usable for the "Canada" geo data. Simplifier uses >5.0gb of memory to simplify that dataset with DouglasPeucker(tolerance=5000) + Constraint Preserve Topology...

- Auto detect snapping points - Auto detect map size. With SRID=4326, 0.01 is less than 1 km so it's a good starting point. With other projections, the default value...

Note: Make sure to not allow user to overwrite the original source and lose it

This will make it easier for the user to find thresholds and configuration. The idea is to preview into a new window, with ~5 geometries being simplified.

Will reduce memory usage and make it faster to simplify in some cases

Sometimes, when simplipy crashes, the plugin becomes unusable and the only way to fix it is by restarting qgis
