Robert Cerny has released Topincs 5.4.3.
From the release:
This version simplifies the Topincs help system. The self-explanatory nature of using Topincs leaves the help usually just as a list of available keyboard shortcuts. The help can be accessed with Alt-Shift-H or Alt-Shift-Control.
In addition some bugs were fixed and the access to resources (like images) for styling a Topincs store was made possible.
