Compatibility of ShowInOut with SenderName Rated 5 out of 5 stars

The SenderName 0.4 extension (https://addons.mozilla.org/en-US/thunderbird/addon/5296) that was recently updated to work with Thunderbird 3.0 seems to break the ShowInOut 0.7.3 extension (https://addons.mozilla.org/en-US/thunderbird/reviews/display/3492) extension -- there is no crash, but the new columns of ShowInOut are no longer available. Not sure which extension is responsible. Both extensions are excellent and I think many people would want to use them concurrently.

This review is for a previous version of the add-on (0.7.3).
