Code review comment for lp:~therp-nl/web-addons/trunk-web-hide-buttons

Sorry for forgetting about this merge. Just ran into this while searching for the exact way to do it in v7.0.

Indeed it's not available for 6.1 but I wanted to suggest mainly to use the same words to avoid more migration work when moving from v6.1 to v7.0 but alas ... :)
