It seems like these surveys crop up every other month or so. Since Google Sites received a recent update with the new "Edit Site Layout" option in the More button, they must be listening to the community of Google Sites users. That update was more of a convenience than anything, not a new feature, but I use it all the time now, especially on adding links to my Horizontal Navigation.
Anyways, please take your time to fill out the Google Sites survey the best you can. This feedback will undoubtedly point the Google Docs team to implement most wanted features.
How would you describe Google Sites in one word?
Most often I choose words like: efficient, easy, versatile. Tell me what you think and stay tuned for more Google Sites news.
