Hibernica:

1) Don't update the image. It isn't meant to be updated. There are many problems with trying to update the image, one the worst of which is the fact that OpenOffice no longer runs. Many of the problems are the fault of the Debian armel Sid distribution, which seems to be in a particularly bad state right now.

2) Performance mode sets the processor governor speed to 400 mHz, so it will always run at full speed, instead of regularly falling back to much lower speeds as it does in the "on demand" speed. It is simply a shell script with no GUI. If you provide an easy way to display a hildon banner from the command line, I will use that method instead.

3) I don't think I should make the N8x0 image any bigger, since the N810 comes with only 2GB onboard. If you want more space, the best thing to do is to partition a card and put the rootfs into the partition.

4) There is no facility that I know of for making new menu folders when installing an app. If there were, I certainly would have done it that way!
