I’d like to suggest a couple of enhancements that would improve the visual organization on the home page:
Option to change the background color of the icons. This would make it easier to visually separate different types of shortcuts.
Option to add spacing between selected rows or group icons per row into labeled sections (similar to HTML fieldsets/legends). This would allow grouping categories such as dev tools, music, dancing alpacas, etc.
After about three rows, the layout starts to feel a bit cluttered. If grouping or spacing becomes possible, it might also make sense to allow more rows overall.
