I already mentioned this 'Toolbar and Toolbox icon' issue to Frank Mariak, and Deron Kazmaier - I seem to remember that being before v5.1.2 was released. I believe Christoph Poelzl has put some effort into some refurbishment of the icons but I have not seen the 'fruits' of his efforts so far.

Deron stated that he is not a graphic designer, and there are methods to re-work the icons for the interface if someone wants to get involved with skills that can benefit us all.

If anyone does want to do some work on the icons, then just get in contact here, and I will pass your details along, that's if I am not in any case able to pass you the actual icons that can be re-worked to be improved upon straight away.

Some changes are in the pipeline for a re-worked release, for some of the known issues that have been reported, but these are under close wraps at the moment, and even I do not know what they are.
