martinK: I have been using modrana a lot over the past few weeks, and I have a few suggestions for what would make it perfect in my opinion at least.

• Add a view option to rotate map to heading (instead of being always north-up).
• Add customizeable callout distances. E.g. I might want a callout at 50 yards, one at 500 and one at 2000 but other people might want them in different places.
• Have eSpeak say the number of yards that triggers it, not the actual number of yards. For instance, if a callout is at 300 yards and eSpeak is triggered at 297.4 yards, have eSpeak say 300 anyway.
• Aesthetic thing: Split numbers at the two digit mark, so for example 422 is read "four twenty-two" instead of "four hunderd and twenty-two".
• Hardware acceleration.
• Smooth zooming (i.e.just scale up the already loaded tiles and then replace them with higher resolution ones when they are loaded).
• Determine point reached distance based on speed (so the radius at 60 mph is three times that at 20 mph).
• I don't know whether this is possible: Load the traffic layer from Google Maps?\

Are any of these currently in the works? I would be glad to help if you would like.
