When shadowsocks-windows starts up, it could check if the user has copied an ss:// link to the clipboard, so it could proactively offer to add the server when it detects a new one. Something like:

Better yet, instead of just checking the clipboard once on startup, shadowsocks-windows could monitor the clipboard while running, so if a user copies the link after starting shadowsocks, they can still get the offer.
Similar to function 'import URL from clipboard'

Yes, similar to "Import URL from clipboard", but better because it's proactive. This saves a new user from having to navigate through two levels of unfamiliar menus and a total of 22 different menu items to find the one they're supposed to click. It may seem like a small change but the usability of the feature will improve dramatically.
I see this issue got some thumbs up over the last week. 👍 😺
ss-win maintainers, would you accept a pull request that implemented this?
To be honest, I don't think it's really useful. KISS.
If by KISS you mean "keep it simple, stupid", that's my same motivation for opening this issue. Right now accomplishing basic tasks is unnecessarily complex, especially for new users.
Keep watch clipboard may cause other software crash, e.g. Clipboard.SetText may crash because a download software watching clipboard.
Watch clipboard constantly isn't a good idea, we are not software like Thunder. BTW, you can import multiple servers via "import URL from clipboard"
