I know there are few threads asking for this but I wanted to create a new one to stress this.
PLO5 might not be the most popular game, but popular enough that it should be supported.
And from 'Max Value Software' perspective it might be a wise decision since none of the trackers I know support PLO5 currently and thus it might increase sales of this product.
I would be just fine even with most basic - tracking the results.
Unfortunately I do not have an estimate for if/when this feature will be added.
