Aligning text and icons across widgets

Is there a simple way to have all widgets have two lines for text, even if the text only needs one line? In order to get the text and icons to line up across widgets? Or to bottom align all the icons?

No simple solution, but you can add a piece of CSS like

.switch-content > div:first-child {
    height: 4rem;

in a file in e.g. $conf/html/mystyles.css and reference it as an additional stylesheet in the settings (/static/mystyles.css).
Note that it will affect all switches, and switches only. You would do something similar for dummy/buttons - though it might be a little different, use the dev tools inspector in your browser.
