Lepinard, all you will see is the speed difference between SOG and STW.
That means the "current" display will always be directly from bow or stern,
in other words the component of the current
along the centerline of the boat
, assuming your STW(speed through water) is calibrated correctly.
And all of the polar based functions rely on compass
heading and STW.
So I don't really think it makes sense, as the informations will lack reliability
(it is already error prone due to possible calibration issue).
I can put it on my list of todo's but it'll take a while. I have only limited time, and I'm still struggling to get the laylines-to-waypoint going and to lift
the whole plugin on github.
And when that's done, we should get it going under linux
But you can simply give it a try and use the NMEAConverter plugin to create a HDG (compass) sentence from your COG.
That's the easiest and quickest way for now to get you going.
