Clearing the debugger call stack

[280Z28]

There's no way (that I see) to clear the call stack history. I like that I can go back to previous traces, so I don't want it to automatically clear. A button that says "Clear Window" next to "Save to File" would be perfect.

All debugging windows are now kept in sync at all times

This means it is automatically synchronized with the debugger. That's also the reason the "Refresh" button was removed.
If you want to keep a trace handy, save it. Or a "copy to clipboard" function would be more appropriate?
