Heuristics are hidden behind so many elements of the map nowadays. As a result, editors are often expected to read multi-page documentation to understand how to take advantage of them or how to avoid unintended behaviour. In practice, even experienced editors frequently are unaware or uneducated, making this expectation especially unrealistic for new editors.

My suggestion is to eliminate heuristics altogether, and replace them with auto-generated explicit paths/TIOs/etc. Whether it's an H or an # junction, traffic lights, turn instructions, u-turns, etc, everything should be visible and unambiguous in the editor.

Some examples:
1) if a u-turn in an H junction is prohibited due to the length of the median segment, WME should display a red (prohibited) path when the relevant segment is selected.
2) when selecting a traffic light hazard, WME should display which 'Visibility' and 'Voice instruction' option apply to each path.
3) for turns, WME should display the selected 'Voice guidance' (e.g. exit/keep/turn right).

In tandem with removing heuristics, "Waze selected" should be eliminated too. Instead, WME should preselect and display the actual option that will be used, increasing transparency and predictability.
