Localization of Widgets Plugin and Role Manager Plugin

I’m in the process of localizing the Widgets Plugin and the Role Manager plugin.

In the Widgets Plugin i’m stuck with the different default widgets like “Categories”, “Pages”, “Recent Posts” and so on. I find them in widgets.php but wrapping the strings with __() or _e() just doesn’t do the trick.

The Role Manager plugin itself was easy to localize but the different capabilities like “Edit Posts”, “Manage Users”, “Edit Categories”, etc hold me back from finishing it. Where can those strings be found?

I hope, someone can help me with the remaining strings…
