Simple widget to extend P2s (and other themes) functionality and display recent @replies for a logged in user in the sidebar. 
It can be also configured to show direct replies to comments or posts without the @username indication.

Mention-Me Widget

11-year old plugin and it still works just fine! Sweet!

It works!

P2 Resolved Posts is a lightweight GTD plugin for WordPress and the P2 theme. Mark a thread as “unresolved” when there’s something needing to be finished, and mark it as “resolved” when it’s been finished.
Sidebar widgets allow you to see all unresolved posts, optionally filtered to a specific tag.
Watch the audit log to see who is doing what.
P2 is a great tool for communication and collaboration. P2 Resolved Posts makes it easier to better understand when a discussion has reached completion.

P2 Resolved Posts

Nice widgets and simple but fine feature for better collaboration in P2. I wish users could set the tag filter of the widget in the front-end too, instead of just in the settings. I guess I'll have to do this part by myself.

Simple and easy

Lightweight GTD for the P2 WordPress theme.
