gaffka You can't edit a contact from the Recents tab.
You can't edit a contact from a search result in Contacts. (must browse to the contact)
Favorites thumbs are ginormous. Would like a simple "List" option to fit more without scrolling. (or smaller thumbs)
Would like a "Confirm" option when making a call. (made so many erroneous calls while trying to edit a contact from search results or recent call list)
I currently use Right Phone by Goodwy with all of these features working (tested them just now). You have to make a few adjustments in the settings to get it to work this way, but I love the fluidity. It also looks really clean and polished.

He also has developed a Right Contacts app, Right Messages, Right files, and Right Gallery that all mimick the look of iOS which looks quite slick.
As for call the other features like call merging, and notifying if another call is received will on a current call, I have not tested yet.
Hope this helps,
