Continuous, variable zoom in Bridge

We're way past the 90s, so how about implementing a variable zoom instead of just 100%, 200%, 400% that we know from Windows XP. Sometimes when you show photos to clients, you just want to zoom a little bit in and not all the way to 200%. For this use-case, it would also be nice to have an option to toggle between pixel interpolation on/off.
