Issue #1:
The Turn Counter was never designed with HTML in mind and has never supported it. It would make it extremely difficult to manage the floating and docked mini-window sizes. This is not something that will happen soon.
Issue #2: I think you are talking about the ‘Button Text’ not the ‘Name’ which is displayed in the Turn Counter Window? The maximum feature is designed to allow for the maximum expected value in Turn counter itself. Up to you to control the title and width, we don’t have much control over the Window title bars across platforms.
Issue #3: probably easiest to add a Description field for the designer to use.
Issue #4: Yes, definitely something wrong there.
