My apologies if this is a duplicate request ... On the web interface e.g. http://localhost:8888/gui/ (using firefox) I see a list of my folders and a column labelled Sharing. In the Sharing column, there are three buttons, 1- Get secret, 2- a gear, 3- a red X. These should have hover-help hints for what will happen when I click on them. Right now the red X drops the shared directory immediately. The little left/right arrows and up/down arrows shown when syncing is being done would also benefit from hints that say more about what is happening.
