If it isn't too much trouble please show the connection speed when updating. Sometimes because of the connection its quicker download the file from a browser of download manager.

Currently it takes a bit of calculation/guesswork to tell the transfer speed (and by extension the time remaining)

Ok, I add it to my todo list.

But I plan to make incremental updates in the future. This way, the file to download will be much smaller, and download will be fast even on a slow connection.
