Location of send buttons in input area could be improved

[Gilbertdelyon]

Native configuration of input area is not convenient when you use it in narrow sreen (smartphone) because there is a significant lost space.

I would suggest this style which is much more convenient in my opinion

I simply added these lines in custom theme.css

.mail-message-form .humhub-ui-richtext {
    padding-right: 5px !important; 
}	

.mail-message-form .upload-buttons {
    position:  static !important;
}
