Often scrolling the Markers-panel is extremely slow, which is weird since they are just markers. I suspect generating the thumbnails is what is taking most of the computing power – everything else is just text in there. I rarely need the images; color coding and large text boxes are the tools I need when browsing markers.
Option to toggle the thumbnails with only the marker color flag would be welcome. (At least if I'm correct and that would fix the performance issues with that panel)
