We have some questions on the filter functionality:

1. What keywords would you like us to include in the filter? Would this just be name or surname or would you like us to incluse anything additional
2. When we filter, please can you confirm that it is preferred that the unfiltered graves are not hidden?
   Do you have a preference to the colour that we make the unfiltered graves (grey is an obvious colour, but shows the unavailable grave)
   Would you like us to update the ledgend with the unfiltered graves to be included during the filtered process?

This is what the filter looks like currently:

@meomancer

Keywords should be "name" or "grave ID"

Add a bright yellow outline to the graves included in the filter and leave the legend and colours as it
