= Legend

Sowa1980 came up with an idea to show explicitly levels tags while editing building. Showing them allow to see in a convenient way which tags are not set without selecting individual objects.

* [[span(style=color: #357c23, Greenish)]] colour is for building related tags.
* [[span(style=color: #1d82df, Blueish)]] colour is for building part related tags.
