The literature for the Level Tool suggests that the more the level line is extended, the better the accuracy. With that in mind, I find it a bit cumbersome to go back and forth across the image to move the end points in gross movements until the line is in the exact position (yes, I am a bit OCD....).

I was wondering if, like when Compositing two images with One Point movement, there is a way to move the end points with an up/down icon (although Composite has up/down/left/right icons and I think one can even do a half pixel with the Shift key, but I may be mistaken on that). Perhaps initially placing each point in the general location, then using the up/down icons to finish. Doubt 1/2 pixel is necessary but even 5 pixel increments would be worthwhile??

A feature to deal with this was added relatively recently. First place the line endpoints crudely with the entire image visible and then zoom in to 1:1 or higher. If you press "1" or "2" on the keyboard, PWP will recenter the image on either the first or second endpoint and you can drag them right where you want them. At a high enough zoom ratio it's pretty easy to place the line precisely.
