[Improvement Request] Add cover folder indicator

[SelfRef]

Description

I love cover folders feature since I discovered them recently. I have used them extensively on Action Launcher before. Although after enabling some of them I have trouble to remember which icon is a cover folder and which is a regular icon.

Expected Behavior

Action Launcher has a neat little indicator that tells user if icon is cover that hides folder/widget under gesture. It would be nice to add a similar indicator in Neo Launcher so it's more obvious.

Actual Behavior

Cover folders don't differ from regular app icons.

Steps to Reproduce

1. Create cover folder
2. Forget it's a folder and search hidden app in drawer

Device and OS

• Device: Nothing Phone (1)
• Android version: 13
• Launcher version: 0.9.3
• Rom: NothingOS 1.5.4

I would really love this feature!

Would it be possible to have a different shape for the folder group than regular icons? That would be an alternative to an added icon.
