Feasture Request - Timeline zoom percentages

As a reasonably new user of After Effects, the only thing I find frustrating is the 'inexact' nature of zooming on the timeline.
With other Adobe products (and within the comp window itself) you can zoom in in percentage increments.
I find, when working on a project, the tiny zoom at the bottom of the timeline is so small and inexact, I only really use it like a 3 stage zoom, all the way in, medium and all the way out. Anything else is quite finicky.
The time navigator (above the timeline is far more useful in that you can drag in or out the view with greater control because it's larger.
WHAT ITS MISSING FOR ME IS A box to type or select a percentage. (15%, or 25%, or 50%)
This would allow me to use a common percentage for my comps that suits my specific comp.
Depending on the length of my comp I quite often use the SAME PERCENTAGE because of the scale of my effects, or clips or the timing of my animation. If I could easily zoom in 25% it would make my life much easier.
You could incorporate a percentage based zoom at the bottom (might be a bit tight), or even a tool-tip type calculation at the top to tell you WHAT percentage when you drag the time navigator (see my mockup).
This would at least tell my brain to 'zoom into around 20%' to see my elements at the scale I commonly use.
