When pinning while the maximum number of pins is already reached, no error message is displayed

[narFnarF]

Steps to reproduce:

1. Pin a message
2. Keep pinning different messages until the maximum is reached (normally 5)
3. Pin another message

Current result: No error message or warning is displayed.

Expected result: A warning is displayed, explaining that the maximum number of pins has been reached

On a similar topic: Currently, no success/confirmation message is displayed when pinning a message (while under the limit). It would be a nice addition.
