Three fixes from your reports

All three of these came straight from your reports on 0.22. The v1.0 beta is open for exactly this, so keep them coming.

New

Show charging watts in the menu bar. A new Settings toggle puts the live wattage your Mac is drawing right next to the menu bar icon, so you don't need a second app for it. Off by default; flip it on under Settings. Thanks @sinfojo (#316).

Changing the menu bar icon no longer misaligns the popover. Icons are now pinned to one size, so switching between them doesn't shift the button mid-session. Thanks @slynn1 (#313).
Honest wording when macOS pauses charging. With a battery charge limit or Optimized Battery Charging holding the battery, WhatCable used to say "Charging well". It now says "Plugged in, charging on hold" and explains why, while the port still shows the power your Mac is drawing. Thanks @HaoXuan0001 (#319).
