You can bend the line tool lines in Photoshop? How?
You can either:
Click and hold in the left mouse button, drag in any direction and continue doing so
Click somewhere hold Alt and click and drag on your square then click somewhere else to see the bent line
Place 3 or more squares and hold Alt over a square between the start and end squares and click and drag in a direction
If you want to move one circle at a time, hold Alt and drag the circle or if you want to move both, hold Ctrl and then drag either circles
Besides, the pen tool in Photoshop can make lines much smoother than that.
No it doesn't, not unless you're filling in the path instead of stroking it with the brush's settings, the brush can still make ugly blurred lines with spacing at a minimum and hardness at a maximum, you're best using a 1 pixel line, 2 and up seem to make said ugly lines
