thanks for this feedback and for trying out the toolbox! We already realized this on a windows machine and adapted the GUI, which has been made on a mac, a bit. However I took the opportunity to re-model the whole GUI to have more space and to get a clearer overview of the workspace this morning. I also entered some tooltip-strings, so if you hover over the GUI elements now, there should be some help displayed. I’ll send you a download-link for the new version soon. Please tell us if the GUI still feels crumpy, because this is very important for the overall user experience, of course.
