Improvements for copying logs directly from window and reconnecting behaviour like in orginal monitor

Hi,

Thank you for your version of Serial Monitor, it's awesome. As per topic, would be nice to have improvements for:
- pressing Ctrl + A to copy whole log text to clipboard, in currant state it copies text from all the buttons 
- reconnecting after pressing enter, when disconnected. This behaviour was in original Monitor, would be nice to have it here

Cheers,
Chris
