Localised titles

Hi, I’m trying to figure out how to localise some titles. My Dropdown Menu plugin has been causing issues for non-English blogs as the titles for ‘Pages’, ‘Categories’ etc. are all hard coded into the plugin at the moment, so the only way to change them is to hack the plugin PHP file.

Any ideas on how to set it up so that the titles will be labelled according to whatever language the blog is running on at the time?

Thanks in advance for any help 🙂
