Some times I want to draw some precise lines (e.g. holding shift to create straight lines) with a big brush. Unfortunately, the cursor for the brush is just a big circle, which makes it very difficult to pick a particular pixel because you don't know precisely where the brush centre is. At the moment I'm quickly switching to "pick colour" mode to place the cursor when I want, to then turn off pick colour (without picking any colour) and keep mouse in place. But this trick doesn't work with the eraser ("pick colour" doesn't activate with the same shortcut).
A suggestion to solve it
Maybe you can change the UI of the brush circle to incorporate a dot (pixel) in the centre. That way it'll be trivial to place the centre of the brush at the exact pixel that you want.
Thanks for your time!
