I make my own "mini panels" for flying outside the aircraft. One gauge ... Cessna!Heading_Indicator ... has stopped working in V5. The settings button will not let you change the heading. This can be fixed by substituting that one with ... C1855!Heading Indicator ... which works in V5, is the same size and works the same.
But there is another change, if you are replacing gauges, that you must know about. Before, when you made a change in a gauge in the panel.cfg file and saved it, you simply went into the sim and clicked on SELECT Aircraft and re-select the one you are working on, when it comes up, the replacement gauge will be there. BUT NOT SO in V5. You cannot see your work by simply doing Select Aircraft ... you must select ANOTHER aircraft first, bring it up, then re-select the aircraft you were working, then you will see the change. Otherwise, no matter how many changes you make, none of them will show if you are simply doing Select Aircraft on the same sim object.
Heaven knows why it is different in V5 ... but I wanted the very few people who do this to know about it and save themselves an afternoon of trying to figure out why nothing would change.
