Merge tool auto-closes open path shape
I seem to remember this had been added to VS a while ago but it does not seem to be in the current build. I don't know if it was accidentally removed or you felt it was not in line with the vision VS.
I know Illustrator has this option - that if you have an open path fill selected, if you click on "merge" it will close the shape - essentially the same as a control-J
It comes in handy for me when I am dealing with vectors with crazy attributes or issues from external sources - using merge sometimes helps flatten the vector and it eliminates the possibility of an open path being left behind there
@Boldline This can be added (back) easily. I have to check if it is in conflict with some other feature.
By default I try to have each boolean operation to work on open shapes also, but some may not need to.
