@Mark_K ah yes if you have the NW/SW/SE/NE lines in addition it can still be problematic. I have implemented a "short circuit" for straight line gestures, but it wasn't enabled yet. In 5.274 alpha you can try it by naming your gestures either
up, down, left, right, up-left, up-right, down-right, down-left
or
south, north, east, west, north-west, north-east, south-west, south-east
In my tests this has worked well. Maybe I'll add it explicitly to the recording UI.
