The Toolbars
There are two toolbars. The horizontal toolbar positioned at the top of the main window, which allows you to manipulate objects on the canvas (as well as the save, load and new buttons) and the vertical toolbar positioned to the left of the main window, which you can use to create new paths and text areas. If a toolbar is too wide/tall, scroll buttons will appear.
You can show or hide the toolbars or change the location of the vertical toolbar so that it appears on the right of FlowframTk's main window using the Borders tab in the Configure User Interface dialog.
The preamble pane has its own toolbar with buttons to edit the preamble text.
