Thanks for the fixing the security and the template editing issues (+ typo) I reported to you via email. It's a shame that reporters don't get any credit or acknowledgement though, but at least it's finally fixed.
I did however notice one issue I already reported but which didn't seem to get fixed on the latest version:
If you rename a check/sensor on Pingdom, the plugin does not update its name in wordpress, even after synchronisation. I even sent you a patch file that fixes it, perhaps it's not the most elegant solution, but it works. Hope you can also include this fix on the next release.
