Hello Daniel,
1. If I understand correctly, you want a certain section to be visible on phone and tablet, right?
If so, you should choose the “hidden desktop” option, instead of “visible phone”.
2. Unfortunately there isn’t a built-in way to do so, but you can easily do it with a little CSS.
For example, for mobile:
@media (max-width: 768px) {
#header {height: 50px;}}3. Both of the screenshots you sent us are the same..
Are you referring to the border line that’s displayed under the title?
If you want it to be displayed for a widget, you just add thr widget’s title.
4. We’re checking this issue.
5. In Theme Options > Sharing you can edit the sharing panel.
6. Could you send us the page in which these icons are displayed?
