Contacts set up and editing functionality needs improving
Contacts in v8 needs to have similar functionality and the flexibility that v7 had.
e.g.1 v7 allows a non-Skype contact to be set up prior to calling them on their phone number, with v8 you can only create a contact after you've made or received a call to or from a phone number
e.g.2 v7 allows multiple phone numbers to be set up against a contact, but v8 appears to allows only one number
e.g.3 v7 allows you to edit or modify a phone number type such as change a number from being "Office" to "Home" or "Mobile", v8 appears to set the type for you (regardless of whether it's correct) and it's then unable to be changed.
I'm currently able to get around the Contacts limitations in v8 by also having a v7 Desktop set up where I can modify and set up contacts as required. Once done they're then available across any version of v8, whether it's Mobile or Desktop. This works, but it's a little cluncky and far from ideal. Being able to set up new contacts from scratch, or make the required changes, in either Mobile or Desktop v8 would be the prefered outcome.
