For example I use the Developer toolbar shortcut a lot but I only really need the "Responsive Design Mode" and "Web Developer Tools". It would be better if there was an own icon for each rather than a drop-down list. I often use browsers without a keyboard so it would make browsing and working a lot faster and simpler: if you don't have your hand already on the keyboard then clicking a toolbar icon with the cursor is faster than going for the keyboard shortcut. Also a shortcut for "Proxy Settings" would be nice as I often need to turn it on/off and add web pages to exceptions but going through all the settings menus is painfully slow compared to a one click toolbar icon. These toolbar icons would be very easy to make and would help handicapped people a ton as well.
