Display a line in 3D for the seam angle if changing it...

That is actually the only other feature request I would have!

The Angle selection for the seam hiding is a very small dial (and you cannot enter absolute angles).
Depending how parts are placed I want sometimes to 'hide' the seam in a corner or on the back of the print.

But you need to turn the angle, then slice, then look up where the seam is.

Why cant you just display a bigger pointer over the models showing which direction you have currently selected (see below example):

p.s.: Another option is the ability to select next inner or outer corner (the picture above is an outer corner) instead the angle.

Probably can. It evidently seems easy to you. It isn't. It takes is someone to develop the code to do it and that code just might be complex.
