I've been working for a while on a UserScript for adding some useful info onto housing listings in NL.

Thus far I've added the energy label from eponline to pararius + funda.

I'm still working on the following few goals:

1. Add karmernet
2. Add better parsing for addresses, and better matching said addresses on eponline (janky addresses cause issues, and I haven't yet implemented going to page 2, 3, etc of eponline when possible)
3. Add in woz value integration
4. Add in points calculator (maybe with some interactive buttons or something on the page to select bathroom/kitchen quality, I dunno)
5. Put the results onto the listing page not just the search pages.
6. Figure why it doesn't work nicely on kiwi browser (mobile browser)

Feel free to install a UserScript extension manager and install it yourself. I'm using tampermonkey for dev, but it should work in greasemonkey, tampermonkey, and violentmonkey.

If you find an address that it doesn't manage to enrich, please drop a comment or a bug report with the address, or any other issues you bump into
