Thanks for all the replies (while I was sleeping). I will try to address some of them.

As far as units, the numbers are provided in bytes (B) and I do a straight conversion to make a more readable number. Thus for KB I divide by 1000. MB by 1000000. GB by 1000000000. The upload and download could be displayed in different units currently. I have thought it might be a good idea to link them.

As far as having extra data displayed on the widget, I don't think there is an easy and reliable way to get the average rate. I don't have any strong opinion on reset date, but I think it could be handy to some. Maybe a user option to display it?

Fonts and colours are easy to handle programatically. For the title font I use "SystemFont" which follows the theme. For the rest it is "SmallSystemFont". These two fonts are recommended in the Hildon HIG for dekstop widgets. Font colours would be "DefaultFontColor" and "SecondaryFontColor" which are also defined in the theme. Currently I am not using the secondary colour, but I will in the next version.

As for the icon, I will go with the consensus - but anything would be better than the mish-mash icon I made up for the app manager

Edit Oh yes, as for renaming it (again) it would be easy for the app manager and widget itself to display whatever text is chosen. I don't think I will actually rename the package itself, but that would be invisible to 99% of the users.
