The "In QSO with GUI section (circled below) is hard to find and parse.
The location of this section is hidden in the middle of a busy screen. It is hidden vertically between the log and the connected callsign box, with NO white space to separate it.
The font, lowercase, text size is hard to see and read.
The QRZ ? and History and Graph buttons should be a bit larger and prominent.
The QRZ ? button does NOT need a "?".
Please brainstorm some solutions and add to the comments!
Suggestion: Add a QSO timer in the status bar at the bottom of the GUI. (The circled location is just an example. It does not need to be in that specific location within the status bar.)
When connected, instead of putting the callsign in a separate textbox and greying out the callsign above the Connect button -- use the callsign above the connect button as the indicator!
Bold it.
Highlight it in green when connected.
Then remove the additional textbox.
