thanks for the update.

So far I don't see any use in the axis snap, as far as i can tell it can only snap to axis extended from the origin, in 3D view it only works in x and y axis no z axis. So, I would definitely want an option to turn it off.
For now I assigned G to turn of those guides.

When making guide lines to snap points to and you get that box it has options in it, I think it would be nice to include an option to delete the last line, sometimes I accidentally make a line that gets in the way, and if I already have a network I have to reset everything and then rebuild that network of guides.
