Tough day! I probably rebooted my gps over 200 times today. Changing one byte at a time. In the end, it was worth it.

1- It will be possible to have more than one level for a single file or multiple files. Here's one example with File A and File B. Let's call the POI icon in Where-To "My_POI". In each file, there are categories of POI, let's say Cat1 & Cat2 for file A and Cat3 in file B. The tree will look like this:

My_POI
.. File A
.... Cat1
.... Cat2
.. File B
.... Cat3

Under each category, you will find their respective POIs. Garmin did this very well. While under My_POI, you will see FileA and FileB. Clicking on FileA, you will see a new menu with only Cat1 & Cat2. Clicking on Cat1, you will see the POIs fron Cat1. Back to My_POI, clicking on the "All Categories" button will show Cat1, Cat2 & Cat3. Clicking again on "All Categories" will show all POIs from all categories.

2- There will be some backward compatibility issues: it seems the icon in the Where-To has a slightly different format depending if you are using an old device (like 7xx family) or a new device (like 37xx family). It is basically just a minor color issue. Otherwise, I'll provide a user control to decide which format you want.

3- When using 7xx family gps, there is a possibility to have a user defined icon on the map, but this icon does not appear on my 37xx gps. Not the end of the world, but if you are used to have an icon, now it is not there. Maybe there is a way, but all files I inspected did not have it.

4- I was able to embed a fixed logo with my avatar. I was able to sort POIs by categories from within the same file. I still need to work on the full level of categories as described above. Foreign languages and special characters will certainly be an issue. I need to work on this.

Who cares, right? You are probably just interested by the candy! LOL! Well, not there yet, but very close. If things continue like this, I should be done by the end of the Holidays. Maybe a beta in a day or two.
