Hide battery time remaining until calculated

[erinschief]

Bug Request: hide the battery time remaining until the computer has calculated it. When still booting up, the app just shows "N/A" as the time until a few minutes pass and the mac has calculated the time remaining. Instead of showing N/A, could there be an option to hide that text until the time is actually calculated? Or even replacing the "N/A" string with a "..." could look nicer. Purely aesthetic, just would be nicer to see in my menu bar when I wake up my mac.
