When I look at the contact list all contacts are (unsurprisingly) listed alphabetically. Alas, when I try to add a contact to an existing event the picker dialog shows my contacts in no discernible order - which even differs between the web interface and my android device. Can't test it in iOS right now, but I suppose it is a similiar problem there. So I have to use the search function or to scroll through all of my contacts to find a specific one. Please sort the contacts in these dialogs.
I think the contact picker dialog of the web interface would also benefit from being resizable.
The iOS app is already sorting by name. I just fixed that in the web interface, which is available now, and in my working copy of the Android app, which unfortunately won't be available for a couple months because the next update will be a big feature release.
Great, thanks a lot!
