Hi,
At the current state, 'None' is halfway down the list, however when dimensioning small chamfers and lines the default arrow mostly covers the entire feature making it hard to read. To help this I have to click the drop down list and select None and place it collinear with the chamfer. Or scroll down slowly because you just can't hit the right type constantly.
I think 'None' should be the very second type so only a scroll with the wheel would be enough and comfortable. I know it's not a super high priority thing but would make our work (and I hope also many others) fluent and effortless.
Thanks.
