Add "Edit in JOSM" Link

[species]

for POIs
for areas use the Edit on right top?

Does this have an implication on what the purpose of the demo is? If it has a tech bias, sounds good, if its more for the general public, not so sure...

There is no implication. Could you specify?

We already have "Edit" links for the iD with TransforMap presets, would be just nice to support other editors too.
As JOSM is an advanced editor, this would only be shown:

• For the POI-Popups (to modify existing POIs), if the user switches to the "OSM"-tab
• For areas (to add new POIs) if the user hovers over the "edit" icon on top.

Sorry, yes, if there are other edit links then it makes total sense.
