Currently pressing r and hitting the center view button do subtly different things, thoughts on modifying the behavior of one or both and refactoring so that they call the same function and have the same effects?

Pressing r:

Re-centers view around all actors including axis

Re-centers by moving camera while keeping it pointing in original direction

zooms to distance where whole scene fits nicely in view

does not update axis to fit around scene

Pressing center view button:

Re-centers view around all actors except for axis

Re-centers by pointing camera in new direction but not changing its location

does not adjust zoom

updates axis to fit around scene

Since both serve to recenter the view, these differences are likely confusing to the user.

Nice summary

re: refactoring so that they call the same function and have the same effects?

That would be great

I suggest we generalize the behavior associated with "Pressing center view button"

Fixed in r26080. Even without adjusting the zoom value, something is always visible when the center button is pressed (except sometimes when two small, very distant objects are loaded because then there is nothing in the middle).

Added a new issue to resolve slight inconsistency between center view button and 'r' key - see 0004381.
