First try selecting one of the pre-defined workspaces (top right of your screen). I use the General one nearly all the time as the main pods are visible and the others used regularly but less frequently slide out when required. Each pod has a little triangle top right and you can deselect Auto Hide if you need to work a lot on that one for a while, then select it again when that job is done.
There are options such as Dockable for when you want to move a pod around a dock it somewhere else.

If you text isn't wrapping at the edge of the topic pod, you might have set the zoom level. I can't tell you where it is on the ribbon, but look for something like View > Zoom and set it to 100%.
