A few personal thoughts and suggestions...
1. I find the pop-up box, declaring total run time after stopping code execution, merely irritating and never useful. The ability to disable it would be welcome.
2. I only ever use the dashboard panel with the basic 2D components, though associated icon labels would be good (i.e. without having to individually attach and group text labels).
3. As a basic productivity feature, the ability to group-select flow icons and create a new macro from selected would be good (e.g. Select > Right-click > Create New Macro). Possibly coupled with an option to simultaneously convert the selected icons in the flow to the newly-created macro at the same time (e.g. Select > Right-click > Convert to macro), aiding quick hierarchical decomposition and structure as the code develops and grows.
4. Option to remove component icons from the drop-downs (i.e. Different graphical styles unnecessary when only debug indication is needed).
5. If the system panel is deselected, it doesn't automatically load and open if the component is mistakenly directed to the wrong panel when selected (obviously visa-versa to suit others preferring the system panel). Ideally the panel options would be parentally limited by the 'View' options menu.
6. An ability to custom-colour macro tabs.
7. ...Oh, and I2C slave would be welcome

As a newcomer to FCV6 my apologies if I've overlooked/missed anything.
Keep up the fine work gentlemen, and thanks for your consideration

All the best,
