We’ve been building out a **[material calculator inside RW Elements](https://oneeleven.website/calculator/)** for estimating waterproofing systems. The goal was to move beyond a basic calculator and turn it into something contractors would actually use in the field.

Next step is improving the UI/UX — taking inspiration from tools like @Doobox [Rafter Pro](https://forums.realmacsoftware.com/t/new-web-app-for-carpenters/55250) (super clean separation of results vs inputs, high contrast summary area, etc.), and adding a **“Copy Summary”** feature so users can drop estimates straight into emails or proposals.

This has been a fun one to build, and honestly its starting to feel more like a real tool than a typical site feature.
