My main issue is with Twitch and Messenger sidebar notifications (Don't use the other available social media shortcuts so idk how they look).
Messenger:
When using the "White Wolf" theme (black background, white trim) it's easy to not notice when you have a notification from Messenger because it blends in very well with the blue-white messenger logo. It's even worse when you use a blue trim.
Twitch:
The latest update (don't know what version, can't find the version number anywhere) made the notification pretty much unreadable. It gets a bit better when you open it but doesn't stay that way for very long. Check reference pictures below
When you haven't opened Twitch.
When you have opened Twitch (stays this way for about a minute).
Blue trim:
My suggestion/request:
Make it so we can choose the color and opacity of the sidebar notifications.
