1. Is this request related to a challenge you're experiencing? Tell me about your story.

I regularly use Cloudreve's "My Shares" page to manage the share links I've created. Over time the list grows, and it's especially confusing when I create multiple share links for the same folder with different permissions -- which is a very common pattern for me:

• One link for client A: download-only, no password, 30-day expiry
• One link for client B: preview-only, with password
• One link for internal teammates: download, with password, long-term

In the "My Shares" list, each row only shows the target file/folder, the link, and the permission badges. I cannot tell at a glance which link belongs to whom -- I have to click each one and inspect the permission settings just to remember. After a while it's basically guesswork.

2. Additional context or comments

Requested feature: Add an optional user-defined note (or "alias" / "label" / "description") field to every share, so the owner can label their own links.

Where it should appear:

• In the create-share dialog: an optional single-line input for the note
• In the "My Shares" list: show the note next to or under the share name
• On existing shares: allow editing the note after creation

Naming: note / alias / label / description -- whatever fits the existing product vocabulary best.

Scope: personal/private to the share owner, not exposed to public share visitors. Optional, so existing shares can remain empty.

Length: ~1-100 characters feels plenty; no need for rich text.

Suggested MVP: start with "show note in list + edit-after-create" if a full UI rework is too much.
