What steps will reproduce the problem?
1. Load data in an area with high detail
2. Zoom in
3. Try to edit

What is the expected output? What do you see instead?

The lines and node activation areas to get thinner/smaller, so that it's easier to edit there there are high levels of detail.

I don't think so. If lines get thinner/smaller on zooming in, then they must get thicker/bigger on zooming out, which doesn't make sense at all.

Please provide a lat/long of somewhere that is difficult to edit.

Around Liverpool Street Station in London was where I had the issue: When zooming out the current behaviour is good, when zooming in beyond the standard z18. Once you get to 

Other areas that have lots of shops in town centres for example can be a little hard to select the right item, or move and adjust nodes/ways. Similarly where there are parallel ways, but not close enough for the selector to be used, it can be hard too.

Thinking about it more, the thinner lines would help when moving things more than the selection. Probably as a separate bug, the boundary for when to show the selector of which item you tried to touch possibly needs adjusted.

I also had difficulty editing area with many overlaping ways. I suggest that from a certain zoom level onwards the lines would remain the same width. Like 2mm or sth like this.

+1. When zoomed in very far, it gets very difficult to precisely map ways. A great example is adding buildings. Open up Vespucci and try and add a building, and the issue should become very obvious. I also agree with the previous post: the "get smaller" should stop at a certain point, so the width doesn't get so small that you can't see it. Similarly on the opposite end, there should be a limit to how wide a line gets.

Nodes should scale too. There's no need for a node to fill up a quarter of my screen when I'm trying to edit at high zooms.

A simple (configurable) cap to the maximum stroke width seems to work good enough. Commited.
