Do you know maybe if there will be another update that could change the current layout ?
There is a planned release on the new JS Bar for site visitors which will allow for the ease-of-sharing. This won't adjust the existing appearance of your site as such like the latest updates, but will add a new toolbar.
It would be great if we could bee informed about the planned changes that could
affect on the appearance of our sites.
We announced the recent (and still upcoming) system updates here on the forums earlier in the year. You can read about the still to be released updates here: http://forum.ucoz.com/forum/3-16583-1
