Enhancement - add property spaces analogical to tag spaces

[secretresponder]

it would be great to have a possibility to use spaces by property from frontmatter.

for example, i use tagnotes, which means i have no tags but special class of [[notes]] i use instead in frontmatter. it is very convinient to use with graph view, especially with https://github.com/ElsaTam/obsidian-extended-graph

you may integrate the intefrace layout from it too

looks pretty enough frontmatter: type: operation type: area ...
