You can now mark points using ENTER, and when two points are marked, you can then run the solver with those two X values as starting guesses (press Shift-7), or run the integrator with those two X values as limits (press Shift-8), or zoom in with those two points marking the corners of the new view rectangle (press 0).

Just some early comments.

Tried with a very simple equation Y=SIN(X) both in DEG and RAD mode.

Integration works quite fine (very nice the shading of integral area), even though not as fast as other operations (tried with FIX 5).

The solver, of course, tries to solve analitically the equation if possible and this causes the result being stuck to 0 regardless the selected points.
Forcing numerical solution (Y=X*0+SIN(X)) gives the desired root.
(BTW: is there a way to set the solver to always avoid analytical solution?)

No extremum identified, but i suppose this is the correct solver behaviour.
