Merge edit and view experience; change view-visualization

[tordans]

Even after a while, I am still struggling with the two modes of "view" and "edit".

I would like to discuss to change this part of the app.

Some things I think could be improve:

• In view mode, I cannot see or click on non-tagged lanes. This means, that for some sections of Berlin, the map only shows the background, no other data. As a user, I don't know if there is an error loading data or nothing there. This is also an issue, since the view only display the condition-tags, but if the basic parking direction tags (parallel) are preset, the lane is not highlighted at all (even though some data is present).

To solve this, I suggest to always use the editor-query that shows all lanes, but change the way the tags are presented on the map based on the view vs. edit mode. The non-tagged lanes would become visible and clickable in view-mode, but are only displayed very softly. The info-panel in view-mode could say something along the line of "to tags preset, yet, please add edit to add tags" with link to edit mode.

• The edit action is hard to find. But once the change above is done, the info-panel could become the entry point for the edit action in all cases. There could be a section in the info-panel, that has a short intro and an edit button. Something along the line of "Edit this data. Everyone can edit with a free OpenStreetMap login. Thank you for contributing to this free and open data set."

The edit checkmark could then be removed in favor of this more visible entry point to editing.

@zlant and maybe @jakecoppinger let me know what you think. Thanks.

It may be possible to add a panel that no data was found and a proposal to edit the map

Or if little or no data, then enable edit mode

I plan to add regular parking lots in the future. This would improve the content of the map.

It would be nice to connect the background from iD-editor here with loading data by tiles, history of changes, supporting relationships
