IMO If we ever expose a UI with that much detail to the user we've lost. That's wayyyyy too complicated for the vast majority of folks when they're just getting started (sure, in an advanced panel in settings, no problem).
The entire concept of a "channel" (let alone the duration of it or the size of it) should never be exposed to 99% of lightning users, and IMO the quicker people accept that the quicker LN will actually see some real users.
