Some icons were still not working, this has been fixed. The search paths for the application files has once more been tweaked to behave better with Linux usage. The ini files panel now shows the path centered, italic and on a neutral background. The pre-defined buttons roles have been set where possible/applicable. When a workflow external application run is fininshed, the application notifies the user (blinking taskbar icon, bouncing cursor, etc depending on the platform). The XML validation had a bug: it converted the bytestream to the local encoding when it must be to utf8. And finally, some more micro-optimizations.
