The new line tool is unusable for OPEN polylines and dashed lines.
I understand the wish by Photoshop to create lines that work the same way as in vector programs, where you can draw a line and then change its thickness.
However, the way it was implemented, it is impossible to create open shapes, ones in which the first and last points are not connected.
If I try to use the pen tool, it always creates closed shapes. there is no way to create an open shape.
If I try to create it segment by segment using the line tool, it's also impossible: once I created the first segment, the two end points become active and it is impossible to draw another line becasue when you click over the end of the last line all you can do is move the last line's endpoint.
the only workaround is to create separate lines and then move the vertices to overlap - this is time consuming and infuriating.
As for dashed lines, again the fact that all shapes are closed makes it impossible to apply on lines. the dash is applied twice - once in each direction - on each line, and you end up with either a continuous line or a dashed line with uneven dahses.
Lastly the fact that a selected line always has transform frame around it with no way to turn it off means that it's impossible to drag svery small shapes, you try dragging and end up rescaling them or dragging the rotation center. in vecror programs, the transform frame is always visible as well, but you can deselect and then click-and-drag a shape. in photoshop you can't click and drag, you have to select first.
The bottom line is, as much as getting photoshop to be more like a true vector program in its treatment of shapes is a noble intention, implementing only partially and ignoring elements such as open/close shapes causes the updated tool to be much, much, worse that the old one from multiple use cases.
At the very least, preserving the old way things work should have been possible.
