It's all good! It's true sometimes some things are lost in translation on the internet, but no harm done.
With regards to the labels, I was referring to some that are visible in your screenshots. I've attached your image alongside how it is supposed to look. It looks correct on my screen but my resolution is only 1080p and I'm assuming you have a 4k screen or something, and Windows must be doing some weird scaling. We tried to fix this in OP Config release 0.94 (actually it was
user FuzzyJack in this thread). A lot of improvement was made but apparently there are still some quirks.
I think the TCB could absolutely be used in a model boat and I have often thought I would use one if I ever did make a model ship. There is nothing specific that was implemented towards that end but the board is general-purpose enough that you are only limited by your imagination and number of channels you have on your radio. Obviously directional control is no problem, nor are lights and sound. The turret channels could be repurposed for other moving items on board, for example a winch or anchor.
