We're building out a new website and while using layered navigation we discovered something odd. If we click on a filter and the page refreshes it the ability to filter more similar attributes (e.x. price, color, etc) is gone, because Magento seems to want to unset them.
We've seen plugins but they all use heavily customized code and their own database tables. We would like to accomplish this modification without heavily modifying the code.
Does anyone know which files need to be "rewritten"? Better yet, does anyone know why the core team decided that this would be a good user experience? Every website out there never removes an entire section of filterable attributes. We've tried reaching out to the core team for help, as we have EE, but they're less then helpful. We always get a "we don't support modifications".
