IMO, we ABSOLUTELY need the ability to adjust driving route angle for the snowblower similar to the lawn mower system. Part of my driveway/yard is very long, and Yarbo refuses to drive the path length wise no matter which side/sides I set the snow throwing to(even when using Circle path?!?!?!). Yarbo wants to zig-zag left/right 10,000 times while leaving clumps of snow at each turn location. Most of this would be negated if I could simply tell Yarbo to make long paths from one end of the driveway to the other by modifying the auto path by 90 degrees. This would reduce the time taken to clear this particular area by atleast 50%.
Another setting I would like to see is the ability to set any # of perimeter passes like the lawn mower has, or at the very least, the ability to run a couple final passes over the areas that had lots of zero turn maneuvers to clean up the mess/clumps caused by these zero turns. As a workaround, I’ve added extra Pathways to clean these areas after the main work area is complete.
I think it would also be wise to allow adjustment to the pathing algorithm to add extra overlap to in certain situations rather than depending on equally spaced overlap at all times. Example> In a couple areas of my driveway, the area is slightly wider(maybe 2ft wider in total) at one end than it is on the other….. Right now, Yarbo does a ton of zig-zag zero turn manuvers on each side and 4-5 straight paths down the middle, when it would be better for Yarbo to simply add slight extra overlap to 2-3 paths on each side… This would allow yarbo to to clear the whole area maintaining long smooth paths, rather than adding 50 un-needed zero turn manuvers causing 30-50% longer run time and a bunch of zero turn snow clumps left behind…. I understand that this would probably make the pathing algo much more complex, so maybe the extra overlap would be only needed/added to the multiple perimeter pass function I spoke of above. Extra perimeter passes with variable overlap could help reduce zero turn manuvers needed in many non parallel shaped areas. I’d prefer to see the extra overlap ability be added to the entire path system tho. I’ve drawn a picture to help show what I mean(please don’t make fun of my beautiful drawing 
)
Also, tweaking the turn around manuver would probably help a lot… The core needs to move 25%-50% farther into the previously cleared areas before rotating… In current form, the sides of Snow blower module plows into uncleared snow at EVERY turn, thus leaving the dreaded zero turn clumps in previously cleared areas 
I understand that the path algo in combo with throwing direction is what controls path direction, but allowing us to tweak the parameters to achieve different path options for our particular needs is a MUST HAVE imo. On 2nd thought, Maybe allowing us to draw our own custom paths would be the easiest way to adapt to this problem. There has been many times already where I’ve thought “Dammit! I wish I could just tell this thing how to do it!!!”
Not everyone has a flat square work area, so some software modifications are needed help make it more efficient for those of us with large weirdly shaped work areas and those of us that get LOTS of snow…
Thanks for listening
