Currently the message system displays scroll bars on both the conversation selector and the message itself even if there is no overflow or need for them. Attached is a screen shot showing what I mean.
This is a really easy fix. In the file:
components/com_easysocial/themes/wireframe/styles/style.min.css
simply change change
scroll to
auto in the following selector:
#es .es-convo__sidebar-scroll-area, #es .es-convo__content-scroll-area {
overflow-y: scroll;
}
Auto basically determines if overflow should be used or not. If no overflow, it does not display a scroll bar which makes for a better UX.
