⚬ PROBLEM:
As far back as a couple months ago, according to a post I saw on reddit complaining about the issue, YT has started gradually rolling out a slight change to the information presented on video thumbnail information. They've removed text, replacing it with an icon, put the icon in the wrong place, removed the stylish interpunct divider, and shortened the upload time information. This is how it should look. Ignore the arrows on the left side of the screen (this isn't my screenshot) and look at the thumbnail previews of videos on the right side. Below the channel name, it should say: "XY views · Z D ago", where:
X is the number of views,
Y is the letter abbreviation for amount (K, M, B, or no letter at all for views under one thousand),
Z is the number of D ago, and
D is either minutes, hours, days, weeks, months, or years ago.
So for example, a given video would say "181 views · 23 minutes ago", or "8.7k views · 5 hours ago" or "95m views · 6 years ago". And so on.
This little dot · is an interpunct and it's a nice little divider between the number of views and the upload date.

What does YT have currently?
"► 149k 7mo ago"
It looks HORRIBLE. IMO, it's less clear, less sleek, and harder to parse at a glance. They even unnecessarily removed the interpunct so the two numbers are basically right next to each other.

⚬ SOLUTION:
Write some code that reverts these dumb changes and add it to the extension.

⚬ ALTERNATIVES:
Put someone intelligent in charge at Google, I guess? Someone who won't change UI elements and make them (subjectively) worse?

⚬ RELEVANCE / SCOPE:
I honestly can't imagine anyone preferring the current format. It technically does convey the same amount of information in less space, but... well, I put a "but" there to be my own devil's advocate on this issue, but I hate this change so much I don't want to think of any good points it might have.

⚬ "SIDE EFFECTS":
It shouldn't conflict with anything else.
