Hmm... it shouldn't be, but people keep saying it is, so I believe you :)
I've had some troubles with my laptop recently too.

I'm looking into it, but aside from the issues with how it works by design*
I think the only things we can do are limit the console output and optimise
some of the drawing. With JOSM Imi has used a different approach which
doesn't require lots of redrawing of images and I'd love to see it as an
applet when it's ready...

* I designed the applet the way it is (using Processing) because I wanted
lots of flexibility with rendering, and I wanted it to look like a finished
map. It was all about the interactive features - typing into street names,
scrolling through multiple sets of GPS data from multiple contributors,
animating the progress of an area over time, etc. But that was probably
overkill for the main functions. That's why it's slow anyway, it's
essentially an interactive animation, but that's probably the wrong approach
for a drawing tool :(

It's not currently possible with the tools I know about, but I know it's how
Nick prefers to work so I suspect we will support it in the future. The
issue is what to do if roads already exist - I keep going on about this
because I think it's really hard but people keep asking for it.

You can, I think, use HTTP to POST segments to the API. Perhaps we should
write up how to do this with wget or curl, with the proviso that people
check what exists in the area before doing it?

This should be possible, especially now tracks are cached as images, though
personally I'd like to see it as an option - Steve?

I'm interested on routes around Florence, Italy.


So am I, it's a beautiful part of the world :)

Tom.
