Pin giffgaff staff comments to the top of the comments in Lab ideas.
When a comment is made by a giffgaff staff member it is much more important to note than the many (often pointless) comments which soon demote these staff/ change of status comments so they aren't noticed.
Would take away a small amount of the frustrations of scrolling through the more mindless comments to get to see if giffgaff has updated the idea with a comment
This shouldn't be too difficult to do as there is already a mechanism to upvote comments which promotes them to the top comments.
PS. Edit with an example of recent idea which has had a staff comment https://labs.giffgaff.com/idea/16712751/encourage-users-to-buy-goodybags-without-adding-credit-first No doubt it will get buried soon.
