Re: Change window titles to "Bitcoin-Qt - <purpose>" / misc related renames

NACK. I’ve been clear on this before. End users have no idea what “Qt” is, so it shouldn’t appear that prominently in the interface. It’s just a technical detail. Like putting the programming language in the title.

The focus should be on “Bitcoin” itself, not that it is a UI or what library happens to be used to build it.
